✅ Solutions & Responses

When you ask Qaekwy to solve a problem, it will give you a response. This response tells you if it found a solution, and if so, what it is.

The SolutionResponse

When you solve a model, you get a SolutionResponse object. Here’s how to work with it:

# Ask the engine to solve the model
solution_response = engine.model(modeller)

# First, check if the request was successful
if solution_response and solution_response.is_status_ok():
    
    # Get the list of solutions
    solutions = solution_response.get_solutions()
    
    if solutions:
        # Loop through the solutions
        for sol in solutions:
            print(f"Hooray, I found a solution! 🥳 {sol}")
    else:
        print("No solution found. 😢")
else:
    # If something went wrong, print the error message
    print(f"Oh no, something went wrong! 😱 {solution_response.get_message()}")

The Solution Object

Each solution is a Solution object. It’s a dictionary-like object that holds the values of the variables in the solution. You can access the values of the variables as attributes of the object.

# Assuming 'sol' is a Solution object and your model has variables "x" and "y"
print(f"The value of x is {sol.x}")
print(f"The value of y is {sol.y}")

Other Response Types

Qaekwy has other types of responses for other situations, such as:

• EchoResponse: For echo requests.
• VersionResponse: For version requests.

All responses have the following methods:

• get_status(): Tells you the status of the response (e.g., “Ok”, “Error”).
• is_status_ok(): Returns True if everything went well.
• get_message(): Gives you a message from the solver.
• get_content(): The actual data of the response.
