How to avoid running out of solutions in genetic algorithm due to selection?
The genetic algorithm consists of 5 phases of which 4 are repeated:
Initial population (initially)
Fitness function
Selection
Crossover
Mutation
In the selection phase, the number of solutions ...

How do I determine the genomes to use for crossover in NEAT?
If I have the fitness of each genome, how do I determine which genome will crossover with which, and so on, so that I get a new population?
Unfortunately, I can't find anything about it in the ...

How do mutation and crossover work with real-valued chromosomes?
How exactly are "mutation" and "cross-over" applied in the context of a genetic algorithm based on real numbers (as opposed to just bits)? I think I understood how those two phases are applied in a "...

What is meant by “reproduction” in a genetic algorithm?
In the following exercise, the word reproduction is mentioned.
Your task is to design a simple genetic algorithm, with binary-coded chromosomes, in order to solve a pattern-finding problem in 16-...
