The fitness of any "gene" should be evaluated by the environment rather than by the gene... also, you need to be able to tweak the mutation rate as if it is too high then your fitness gets lost in the noise.
Perhaps you can take A .NET evolutionary computing framework[^] to the next generation

Yes I agree to that! I haven't mentioned a lot about the fitness function. I believe that there can be two possibilities for a fitness function. If the problem is such that it is possible test the correctness of a solution to the problem in linear time, then this function can be used to compare the answers provided by each of these genes with every other gene in the population. Their performance can be evaluated and a specific weight value can be assigned to each of these genes; now these genes can be sorted based on their weight values. After mutation and crossover process, the population size would be greater than it started with. The obvious thing to do here will be to eliminate the low-ranking gene and retain the remaining genes, thereby maintaining a constant population size.
And for cases where there is no specific linear-time function to check the correctness of a given solution to a problem, we would require the user to input the correct result along with the input, to train the population. In this case, the system becomes more dependent on the user's training which is considerably slower than the former case; so it would be necessary that the learning process should require very less epochs.

Yes I also agree to that! Mainly because if we do so, the system would be changing on a random phase. But we require that the system provides more accurate results for each generation. So this can only be done if the newer generation is greatly dependent on the genetic code that proved to be the fittest among others rather than having its code determined by random values. If it were determined by the random values, then the change in the behavior of the population could also be such that it causes a setback to the learning process. The real necessity of the mutation process is to include functionalities that don't exist among the population and need to be introduced.

Mutation is also needed to prevent the population getting stuck in a local "peak".

Yeah, I guess I posted this in the wrong place! This is the first time I am using Code project forum, next time I'll post questions in the right place.

What do I do now that I posted it here? Is it possible to migrate this discussion to the appropriate forum?

How is it that if an octopus only has eight arm-pits they still have ten tickles?

I shall, with temperate modesty, distribute this reply to the occupied space within this forum that, perchance, the one-liners evaporate into the cycling desiccants of space and time, that the process of altering the properties thereof enable comfortable conditions no longer being so modified.
Or, something like that.
