i'm making an AI using N.E.A.T algorithm that plays a game, there is a reporting function in this algorithm that shows statistics about every generation, and one of them is about the best genome, i'm trying to understand what is meant by this line Best fitness: 20201.00000 - size: (4, 7) - species 1 - id 2564, specially the size and id part.

When i went to the file of the algorithm,I found out this is the printing sentence

print('Best fitness: {0:3.5f} - size: {1!r} - species {2} - id{3}'
.format(best_genome.fitness, best_genome.size(),best_species_id,best_genome.key))

but still, I can't understand what theses two numbers mean

  1. The id is simply the ID of the particular genome.

  2. And size refers to (as per the docs) :

Returns genome complexity, taken to be (number of nodes, number of enabled connections); currently only used for reporters - some retrieve this information for the highest-fitness genome at the end of each generation.
