"# of steps in Evolutionary Weighting"
If I have an Evolutionary Weighting node, how can I calculate how many times the inner operators will be executed? It doesn't appear to be a straight product of population_size and maximum_number_of_generations, which would have been my naive guess. What other parameters would affect it?
if I do not completely miss something, the number of applications of the inner operators should be indeed equal to the product of population size and max number of generations if [tt]generations_without_improval[/tt] is set to -1. Did you set this parameter to another value?
Ok, that would be great.
the reason for this is the way how evolutionary algorithms work:
1. pairs of individuals are randomly selected and crossover is performed with a certain probability --> depending on this probabbility a random number of additional individuals (children) will be produced and have to be evaluted
2. on those children mutations might be applied which again will deliver some additional individuals (since RM keeps both the original and the mutated search point) --> again some more individuals to evalute
3. on the other hand, individuals which did not change will not be re-evaluated --> this can even drop the number of evalutions
Since all those things happen randomly, it is hard to say how many evaluations will exactly be performed beforehand.
