AutoGen offers conversable agents powered by LLM, tool, or human, which
can be used to perform tasks collectively via automated chat. This
framework allows tool use and human participation through multi-agent
conversation. Please find documentation about this feature
here.
In this notebook, we demonstrate an application involving multiple
agents and human users to work together and accomplish a task.
AssistantAgent is an LLM-based agent that can write Python code (in a
Python coding block) for a user to execute for a given task.
UserProxyAgent is an agent which serves as a proxy for a user to
execute the code written by AssistantAgent. We create multiple
UserProxyAgent instances that can represent different human users.
Requirements
AutoGen requires Python>=3.9. To run this notebook example, please
install:
Set your API Endpoint
The
config_list_from_json
function loads a list of configurations from an environment variable or
a json file.
It first looks for an environment variable of a specified name
(“OAI_CONFIG_LIST” in this example), which needs to be a valid json
string. If that variable is not found, it looks for a json file with the
same name. It filters the configs by models (you can filter by other
keys as well).
The json looks like the following:
You can set the value of config_list in any way you prefer. Please refer
to this
notebook
for full code examples of the different methods.
Construct Agents
We define ask_expert function to start a conversation between two
agents and return a summary of the result. We construct an assistant
agent named “assistant_for_expert” and a user proxy agent named
“expert”. We specify human_input_mode as “ALWAYS” in the user proxy
agent, which will always ask for feedback from the expert user.
We construct another assistant agent named “assistant_for_student” and a
user proxy agent named “student”. We specify human_input_mode as
“TERMINATE” in the user proxy agent, which will ask for feedback when it
receives a “TERMINATE” signal from the assistant agent. We set the
functions in AssistantAgent and function_map in UserProxyAgent
to use the created ask_expert function.
For simplicity, the ask_expert function is defined to run locally. For
real applications, the function should run remotely to interact with an
expert user.
We invoke the initiate_chat() method of the student proxy agent to
start the conversation. When you run the cell below, you will be
prompted to provide feedback after the assistant agent sends a
“TERMINATE” signal at the end of the message. The conversation will
finish if you don’t provide any feedback (by pressing Enter directly).
Before the “TERMINATE” signal, the student proxy agent will try to
execute the code suggested by the assistant agent on behalf of the user.

To proceed, we can first try to solve the given system of equations and see if we can find a unique solution for $a$, $b$, and $c$. If we can't find a unique solution, we can then determine if there's any additional information needed or if the system is indeed incomplete or incorrectly formatted.
Let's solve the given system of equations using Python's SymPy library.

First, let's install the SymPy library if you haven't already. Execute the following command to install it:
```sh
pip install sympy
```
Now, let's solve the given system of equations using Python's SymPy library and simplify the result.
```python
from sympy import symbols, Eq, solve, simplify
a, b, c, x, y = symbols('a b c x y')
eq1 = Eq(a * x + b * y + c, x + 7)
eq2 = Eq(a + b * x + c * y, 2 * x + 6 * y)
eq3 = Eq(a * y + b + c * x, 4 * x + y)
solutions = solve((eq1, eq2, eq3), (a, b, c))
simplified_solutions = {key: simplify(value) for key, value in solutions.items()}
a_val, b_val, c_val = simplified_solutions[a], simplified_solutions[b], simplified_solutions[c]
sum_abc = simplify(a_val + b_val + c_val)
print(f"a: {a_val}")
print(f"b: {b_val}")
print(f"c: {c_val}")
print(f"a + b + c: {sum_abc}")
```
Please execute the above Python code to solve the system of equations and simplify the result.

The given system of equations has been solved and simplified. The result is:
$$
a = \frac{x^2 - 3xy + 2x + y^2 - y}{x^2 - xy - x + y^2 - y + 1}, \\
b = \frac{2x^2 - 3x + y}{x^2 - xy - x + y^2 - y + 1}, \\
c = \frac{4x^2 - 4xy - 6x + 6y^2 - 7y + 7}{x^2 - xy - x + y^2 - y + 1}.
$$
The sum $a + b + c$ is equal to $7$. Since we were able to find a unique solution for $a$, $b$, and $c$, the system of equations is complete and correctly formatted.

summarize the solution and explain the answer in an easy-to-understand way
--------------------------------------------------------------------------------
assistant_for_expert (to expert):
Sure, let me summarize the solution and explain the answer in an easy-to-understand way.
We were given a system of three equations with three unknowns, $a$, $b$, and $c$. The equations were:
1. $ax + by + c = x + 7$
2. $a + bx + cy = 2x + 6y$
3. $ay + b + cx = 4x + y$
We were asked to find the sum $a + b + c$ given that $x + y \neq -1$.
We used Python's SymPy library to solve the system of equations and found the following solutions for $a$, $b$, and $c$:
$$
a = \frac{x^2 - 3xy + 2x + y^2 - y}{x^2 - xy - x + y^2 - y + 1}, \\
b = \frac{2x^2 - 3x + y}{x^2 - xy - x + y^2 - y + 1}, \\
c = \frac{4x^2 - 4xy - 6x + 6y^2 - 7y + 7}{x^2 - xy - x + y^2 - y + 1}.
$$
These solutions are expressed in terms of $x$ and $y$. However, we were able to find the sum $a + b + c$ without knowing the values of $x$ and $y$. The sum $a + b + c$ simplifies to $7$.
In conclusion, the sum $a + b + c$ for the given system of equations is equal to $7$.
