How to know which generation is the best selected individual. The generation of HallOfFame [0] using deap with the easimple algorithm?

You could track your logbook. The first generation with the fitness (min or max) equivalent to the best fitness is probably the generation at which appeared the best individual.

this is an assumption, I needed something that was certain. Like this: 'hof [0] .getGeneration'

Are you working with a local copy of eaSimple? Like in your other question, have you tried adding the gen to each invalid_ind after both eval(but before hof update) to mark re-evaluated individuals with the current gen.

example:

fitnesses = toolbox.map(toolbox.evaluate, invalid_ind)
for ind, fit in zip(invalid_ind, fitnesses):
    ind.fitness.values = fit
    ind.generation = gen

if halloffame is not None:
    halloffame.update(population)
