Why are these changes needed?

Representing an agent that's encapsulating the Redundant pattern where multiple agents are used to respond to a task and an evaluation agent chooses the best one.

Redundant pattern documentation.

This is a first draft of the approach, it uses a simple 4 step process internally. No swarm/group chat as it is very sequential. If we expand its utility then we can consider an internal swarm.

EvaluationAgent may not be the final name.

Here are the parameters of the EvaluationAgent.

agents (list[ConversableAgent]): List of agents that will provide their responses for evaluation.

evaluation_guidance (str): Guidance on how to evaluate the agents, used by the internal evaluator agent.
    Default is:
    "1. Carefully review each approach and result\n2. Evaluate each solution based on criteria appropriate to the task\n3. Select the absolute best response\n4. You must select a response as the best response"

reply_template (str): Template for the reply to be generated by the EvaluationAgent.
    Three placeholders are available for substitution: [agent_name], [reason], and [response].
    Default is:
    "AGENT '[agent_name]' RESPONSE SELECTED.\n\nREASON:\n[reason]\n\nRESPONSE:\n[response]"

It is currently running a nested chat asynchronously internally, so the agents are all responding at the same time.

school_agent (to evaluation_gather):

The sea looks blue mostly because of how water absorbs and scatters sunlight. When the sun shines on the water, the light is made up of different colors, like a rainbow. Water absorbs colors like red, orange, and yellow better than blue. So, the blue light gets scattered around and that’s what we see when we look at the ocean. Also, sometimes the sea can look different colors, like green or gray, because of things like algae or clouds. But usually, it looks blue!

--------------------------------------------------------------------------------
university_agent (to evaluation_gather):

The sea appears blue primarily due to the absorption and scattering of sunlight by the water. When sunlight enters the ocean, it consists of different colors, each with varying wavelengths. Water absorbs longer wavelengths, particularly red, orange, and yellow, more than it absorbs shorter wavelengths like blue and green. 

As sunlight penetrates the water, the red and yellow light gets absorbed, while the blue light is scattered in all directions. This scattering effect is similar to what happens in the atmosphere, which makes the sky appear blue. The deeper and clearer the water, the more pronounced this effect becomes, leading to a vivid blue appearance.

In addition to sunlight and water, other factors can influence the color of the sea, such as the depth of the water, the presence of particles or organisms (like phytoplankton), and sediment. In coastal areas where sediment is prevalent, the water may appear green or brown instead of blue. In summary, the dominant blue color of the sea is primarily the result of the way water interacts with sunlight, particularly through absorption and scattering processes.

Also, in shallow areas, the sea might look green or brown because of the sand, plants, or other stuff in it. But in deeper areas, it mostly looks blue because there’s less stuff to scatter the colors.

So, it’s basically about how light interacts with the water and what colors are absorbed versus what colors we see!

Here's an example of the compiled responses that will then go to the internal evaluator agent for selection:

evaluation_user (to evaluationagent_evaluator):

AGENT 'gpt_4o_mini_agent' RESPONSE:
The sky appears blue due to a phenomenon called Rayleigh scattering. This occurs when sunlight interacts with the atmosphere, which is composed of various gases and particles. 

Sunlight, or white light, is made up of different colors that have different wavelengths. Blue light has a shorter wavelength than other colors like red and yellow. When sunlight passes through the atmosphere, the shorter wavelengths (blue) are scattered in all directions by the gas molecules and particles. 

Although all colors of light are scattered to some extent, blue light is scattered much more effectively than longer wavelengths due to its shorter wavelength. This scattered blue light is what we perceive when we look up at the sky during a clear day.

During sunrise and sunset, the sunlight has to pass through a thicker layer of the atmosphere, scattering even more of the shorter blue wavelengths and allowing the longer red and orange wavelengths to dominate the view, which is why the sky takes on hues of red and orange during those times.

--------------------------------------------------

AGENT 'gpt_4o_agent' RESPONSE:
The sky appears blue due to a phenomenon known as Rayleigh scattering. This occurs because when sunlight enters Earth's atmosphere, it interacts with gas molecules and small particles in the air. Sunlight is composed of many colors, each with different wavelengths. Blue light has a shorter wavelength and is scattered in all directions by the gas molecules much more than other colors with longer wavelengths, such as red or yellow. Because blue light is scattered more, it tends to dominate our perception of the sky's color, making it appear blue to our eyes.

Additionally, the angle at which sunlight passes through the atmosphere affects the color you see. The effect is more pronounced when the sun is higher in the sky, meaning that midday skies often appear bluer compared to times when the sun is low on the horizon, such as during sunrise or sunset, when the light passes through more atmosphere and the longer wavelengths like red and orange become more prominent, creating a different color in the sky.

--------------------------------------------------

AGENT 'gemini_2_flash_agent' RESPONSE:
Okay, here's the explanation of why the sky appears blue, broken down for clarity:

**The Basic Answer: Rayleigh Scattering**

The primary reason the sky looks blue is due to a phenomenon called **Rayleigh scattering**.

**Here's a more detailed explanation:**

1.  **Sunlight and its Colors:** Sunlight, which appears white to us, is actually made up of all the colors of the rainbow. Each color has a different wavelength.  Red has the longest wavelength, and violet/blue has the shortest.

2.  **Entering the Atmosphere:** When sunlight enters the Earth's atmosphere, it collides with tiny air molecules (mostly nitrogen and oxygen).

3.  **Scattering:** These collisions cause the sunlight to scatter in different directions.  Think of it like throwing a ball at a bunch of tiny obstacles – the ball bounces off in various directions.

4.  **Rayleigh Scattering's Preference:** Here's the key: Rayleigh scattering is much more effective at scattering shorter wavelengths of light (blue and violet) than longer wavelengths (red and orange).  The amount of scattering is inversely proportional to the fourth power of the wavelength.  This means that blue light is scattered about 10 times more than red light.

5.  **Blue Light Dominates:** Because blue and violet light are scattered much more strongly, they are dispersed all over the sky. When we look up, we see this scattered light coming from all directions.

6.  **Why not Violet?** You might wonder why the sky isn't violet, since violet has an even shorter wavelength than blue. There are a few reasons:
    *   **Sunlight's Composition:** The sun emits slightly less violet light than blue light.
    *   **Atmospheric Absorption:** Some violet light is absorbed by the upper atmosphere.
    *   **Our Eyes' Sensitivity:** Our eyes are also more sensitive to blue light than violet light.

**In Summary:** The sky is blue because air molecules scatter blue light from the sun more than they scatter other colors. This scattered blue light reaches our eyes from all directions, making the sky appear blue.

**Important Considerations & Related Phenomena:**

*   **Sunsets and Sunrises:**  At sunrise and sunset, the sun's light has to travel through much more of the atmosphere to reach our eyes.  Because the blue light has been mostly scattered away by the time it reaches us, we see more of the longer wavelengths (reds, oranges, and yellows). This is why sunsets and sunrises often have those warm colors.
*   **Other Planets:** Planets with different atmospheric compositions may have different colored skies. For example, Mars has a thin atmosphere with lots of dust particles, which tend to scatter light differently, leading to a more reddish or yellowish sky.
*   **Pollution:** Air pollution can affect the color of the sky. Pollutants can scatter all colors of light more equally, which can make the sky appear hazy or whitish.
*   **Tyndall Effect:** The Tyndall effect is similar to Rayleigh scattering but involves larger particles. It's responsible for the bluish tint seen in smoke or dust-filled air.

I hope this explanation is clear and helpful! Let me know if you have any more questions.

AGENT 'gemini_3_12b_agent' RESPONSE:
Okay, here’s a detailed explanation of why the sky appears blue, explained from an atmospheric science/expertise point of view. I'll break it down covering the core phenomenon (Rayleigh scattering), some important nuances you often don't hear, and common misunderstandings.

**The Core Principle: RaleighScattering & the Nature of Light**

At its most fundamental level, the sky’s blue colour originates from a phenomenon called **light scattering**. But *how* light scatters is critical. Here's the breakdown:

* **Sunlight: Not One Colour:**  Sunlight, technically "white light," isn’t a single colour. It's the combination of all colours of the light spectrum - red, orange, yellow, green, blue, indigo, and violet (as remembered by the mnemonic "Rainbow"). Each colour represents a different wavelength.  Red light has the longest wavelength, while violet/deep blue light has the shortest.  Think of it like this: red light is like long ocean waves, easy to see and spread out. Blue light is like little, choppy waves.

* **Earth’s Atmosphere: A Particle Jungle:** The Earth's atmosphere primarily consists of nitrogen (approximately 79%) and oxygen (around 21%) molecules. These molecules are much smaller than the *lengths* of the light waves.  This is absolutely key!

* **Raleigh Scattering – The Key Mechanism:** When sunlight enters the atmosphere, it interacts with these tiny nitrogen and oxygen molecules.  The phenomenon responsible for the blue sky is **Raleigh Scattering.** Rayleigh scattering happens when light interacts with particles that are **much smaller** than the wavelength of the light.  This is exactly what's happening with sunlight hitting these atmospheric gas molecules.

    * **Why *Shorted* Wavelengths Scatter?**  The intensity (and therefore the likelihood of scattering) is **inversely proportional to the fourth power** of the wavelength.  That’s a critical mathematical point.  (Mathematically:  Scattering ~ 1/Wavelength⁴). This means shorter wavelengths, (blue/violet), are scattered *far* more effectively than longer wavelengths (red/orange). Blue light, having a shorter wavelength, gets scattered roughly 10 times more strongly than red light! Think of it like trying to bounce a large ball (red/orange light) against something very small - it mostly just continues on.  A much smaller ball (blue/violet light) has a far better chance of deflecting.

**Why Not Violet? The Nuances & Corrections to Common Understandings**

If violet light has the shortest wavelength and therefore scatters the *most*, why isn't the sky violet? It's a great question and reveals some important subtleties:

* **Solar Output:** The sun doesn’t emit all wavelengths equally. Sunlight has less violet light to begin with compared to blue light.  
* **Absorption by Upper Atmosphere:** The upper atmosphere (particularly ozone) absorbs a proportion of violet light.
* **Our Eyes’ Sensitivity:**  We, as humans, aren’t as sensitive to violet light as we are to blue light. Our eyes and brain process the wavelengths, and the blend of the scattering and our perception results in a predominantly blue sky.
* **Multiple Scattering:** The light that *is* scattered doesn’t only scatter once. It scatters multiple times in different directions throughout the atmosphere. This further blends the colours.

**Beyond Blue:  Other Time and Conditions**

* **Sunrise/sunset and Red Skies:** As the sun descends below the horizon (sunrise and sunset), sunlight has to pass through considerably *more* atmosphere to reach our eyes. This longer path means much of the blue light has been scattered *away* before it can get to us.  Because blue light has been filtered out, longer wavelengths (reds, oranges, and yellows) are much more likely to be the colours we see. That's why sunsets and sunrises are often vibrant reds and oranges.
* **White Skies near the Sun:**  If you look almost directly at the sun, the sky isn't blue. Why? Because, at such a low viewing angle, you are predominantly seeing forward, the light hasn't significantly scattered. This area appears white or yellow, which is due to a combination of scattered unscatterred light.
* **Air Quality and Scattering:**  While Rayleigh scattering is dominant, larger particles (dust, pollen, pollution) in the atmosphere cause a different type of scattering called **Mie scattering.** Mie scattering is less wavelength sensitive - it scatters all colors more equally. Higher pollution levels lead to more Mie scattering, which often make the sky appear whitish or hazy.

**Key Takeaways (and debunking common misconceptions):**

*   **"The sky is blue because it *reflects* the ocean."**  **Incorrect!**  The sky's blueness is independent of the ocean's colour.  The ocean *appearing* blue is *because* it absorbs longer wavelengths of light, selectively reflect blue light, similar to the sky's behavior.
*  The fourth-power relationship between wavelength and scattering is critically important.
* Rayleigh scattering only applies when the atmospheric particles are *much* smaller than the wavelength of light.
* It is not violet because of the factors mentioned above (solar emission, atmospheric absorption and human eye perception)

Let me know if you'd like me to elaborate on any particular aspect! I can delve into specific mathematical equations or discuss how this affects the appearance of the sky on different planets if you wish.

--------------------------------------------------

AGENT 'phi_4_agent' RESPONSE:
The sky appears blue primarily due to a phenomenon called Rayleigh scattering, named after the British physicist Lord Rayleigh who first described it in detail.

1. **Nature of Light**: Sunlight is composed of different colors, each with varying wavelengths. These range from violet (shortest wavelength) through blue, green, yellow, orange, and red (longest wavelength).

2. **Earth's Atmosphere**: The Earth’s atmosphere contains gases and tiny particles that scatter sunlight in all directions.

3. **Rayleigh Scattering**: This scattering occurs when light interacts with molecules and small particles in the atmosphere that are much smaller than the wavelength of visible light. Rayleigh scattering is more effective at shorter wavelengths, meaning blue and violet light are scattered more than other colors.

4. **Why Blue Over Violet?**: Although both blue and violet light are scattered, we perceive the sky as blue rather than violet for a couple of reasons:
   - The Sun emits more blue light than violet.
   - Human eyes are more sensitive to blue light than violet light.
   - Some of the violet light is absorbed by the upper atmosphere.

5. **Viewing Angle**: During the day, when you look towards the sky at a low angle relative to the horizon, you see sunlight that has been scattered in all directions by air molecules. This scattered light is predominantly blue because of its shorter wavelength and higher scattering efficiency compared to other colors.

6. **Time of Day Variations**: The color of the sky changes throughout the day due to varying angles of sunlight and different atmospheric conditions:
   - At sunrise and sunset, the sun’s rays pass through a greater thickness of Earth's atmosphere, scattering away most of the shorter wavelengths (blue and violet), leaving longer wavelengths like reds and oranges, which is why the sky appears reddish at these times.

In summary, the blue appearance of the sky is due to Rayleigh scattering, where the shorter wavelengths of light are scattered more than longer wavelengths. The human eye's sensitivity to blue light further enhances our perception of a blue sky during daylight hours.

--------------------------------------------------

AGENT 'phi_large_agent' RESPONSE:
The sky appears blue due to a particular type of scattering called Rayleigh scattering. Here's a simple explanation:

1. **Light from the Sun**: The Sun emits light at all the visible wavelengths, which is why we see it as white. When this light reaches Earth's atmosphere, it interacts with the gas molecules and tiny particles in the air.

2. **Rayleigh Scattering**: Shorter wavelengths of light (like blue and violet) are scattered more by these molecules and particles because they travel in shorter, smaller waves. This is known as Rayleigh scattering.

3. **Why Blue, Not Violet?**: Although violet light is scattered even more than blue light, the sky appears blue, not violet, because our eyes are more sensitive to blue light. Also, some of the violet light gets absorbed by the atmosphere, further tipping the balance toward blue.

4. **Sunrise and Sunset**: During these times, the Sun is at a low angle, and the light has to pass through more of Earth's atmosphere. This scatters more of the blue and green light away, and we're left with the warmer colors of sunrise and sunset, like reds, oranges, and yellows.

So, in summary, the sky appears blue because the blue light from the Sun is scattered more by the Earth's atmosphere and is more readily visible to our eyes.

--------------------------------------------------

AGENT 'together_llama_33_70b_agent' RESPONSE:
The sky appears blue due to a phenomenon called Rayleigh scattering, which is the scattering of light by small particles or molecules in the atmosphere. Here's a detailed explanation:

1. **Sunlight and the atmosphere**: When sunlight enters Earth's atmosphere, it consists of a broad spectrum of colors, including all the colors of the visible spectrum (red, orange, yellow, green, blue, indigo, and violet).
2. **Scattering by molecules**: The atmosphere is composed of tiny molecules of gases such as nitrogen (N2) and oxygen (O2). These molecules are much smaller than the wavelength of light.
3. **Rayleigh scattering**: When sunlight encounters these small molecules, it scatters in all directions. The amount of scattering that occurs depends on the wavelength of the light. Shorter wavelengths (like blue and violet) are scattered more than longer wavelengths (like red and orange).
4. **Blue light dominance**: As a result of Rayleigh scattering, the blue light is scattered in all directions and reaches our eyes from all parts of the sky. This is why the sky appears blue, as our eyes are receiving more blue light than any other color.
5. **Violet light absorption**: Although violet light is also scattered, it is absorbed by the upper atmosphere, which is why we don't see the sky as violet. The absorbed violet light is also scattered, but it is not visible to our eyes.
6. **Color intensity and atmospheric conditions**: The intensity of the blue color can vary depending on atmospheric conditions, such as pollution, dust, and water vapor. During sunrise and sunset, the sky can take on hues of red and orange due to the scattering of light by atmospheric particles.

In summary, the sky appears blue because of the scattering of sunlight by small molecules in the atmosphere, which favors shorter wavelengths like blue and violet. The absorption of violet light by the upper atmosphere and the scattering of blue light in all directions result in the blue color we see when we look up at the sky.
