All the callback functions/methods in PyGAD have limits in the number of arguments passed.
6+
For example, the fitness function accepts only 3 arguments:
7+
1. The pygad.GA instance.
8+
2. The solution(s).
9+
3. The index (indices) of the passed solution(s).
10+
If it is necessary to pass extra arguments to the fitness function, for example, then follow these steps:
11+
1. Create a wrapper function that accepts only the number of arguments meeded by PyGAD.
12+
2. Define the extra arguments in the body of the wrapper function.
13+
3. Create an inner fitness function inside the wrapper function with whatever extra arguments needed.
14+
4. Call the inner fitness function from the wrapper function while passing the extra arguments.
15+
16+
This is an example that passes a list ([10, 20, 30]) to the inner fitness function. The list has 3 numbers.
17+
A number is randomly selected from the list and added to the calculated fitness.
