Question 1

How to implement a custom fitness function in Goga?

Accepted Answer

You need to create a type that implements the Simulator interface, defining a method to assign fitness scores to genomes based on your problem. For example, in string_matcher.go, fitness is calculated by comparing characters to a target string.

Question 2

Goga vs eaopt: which genetic algorithm library is better for Go?

Accepted Answer

Goga is more modular and requires custom component implementation, offering flexibility but more work. Eaopt provides more built-in operators and is easier for quick setups, but may be less customizable for niche problems.

Question 3

Can Goga handle optimization with floating-point numbers?

Accepted Answer

Yes, but you must manually encode floats into bitsets, adding complexity. The library doesn't provide direct support for continuous variables, so bit manipulation is required, as hinted in the bitsPerCoordinateNumber explanation for image matching.

Question 4

How do I speed up my genetic algorithm using Goga's parallel simulations?

Accepted Answer

Set the parallelSimulations parameter in your configuration, as shown in image_matcher.go, to run multiple genomes concurrently. Adjust this based on your CPU cores to optimize performance without overwhelming resources.

Question 5

What are some real-world applications of Goga beyond the examples?

Accepted Answer

Goga can be used for parameter tuning in machine learning, feature selection, scheduling problems, and any optimization task where solutions can be encoded into bits and evolved iteratively, leveraging its customizable components.

Question 6

How to track the best solution over generations in Goga?

Accepted Answer

Use the elite consumer feature, which calls a function after each simulation with the best genome. Implement it to log or output results, similar to the string_matcher example's output that shows progression towards the target string.
