Add statistics to evolution #8

Closed gianlucatruda closed 4 years ago

Stats we'd like to have at the end (preferably in a dataframe with generation as index):

[x] Best fitness in generation
[x] Best fitness so far
[x] Mean and standard deviation of fitness scores for current generation
[x] Some diversity measure

Looks like we want to use deap.tools.Logbook and deap.tools.Statistics

The algorithm takes in a population and evolves it in place using the :meth:varAnd method. It returns the optimized population and a :class:~deap.tools.Logbook with the statistics of the evolution. The logbook will contain the generation number, the number of evalutions for each generation and the statistics if a :class:~deap.tools.Statistics is given as argument.

A :class:~deap.tools.HallOfFame object that will contain the best individuals, optional.

This could be useful too!
