Module: evolutionary algorithm
From SolutionSpaceTool
This module implements a evolutionary optimization concept. Its main function can be called either from console or from GUI(recommended). The function saves the solution files in standard folder for data.

Functions
return generate_evolution_data(functions, parameters, file_info, time_check)
functions: dictionary with functions from datastructure
essential keys: - "randomSolution" : returns a random representation - "changeSolution" : returns a function to change the given representation - "costEvaluation" : returns the calculated costs for the given representation - "recombineSolutions" : returns list of new representations created from the two given representations
parameters : dictionary with algorithm parameters
essential keys: - "parents" : number of parent individuals each generation - "children" : number of children individuals each generation - "generations" : number of generated generations
file_info : dictionary with information about the file names of the data files
essential keys: - "trial_name" : name of trial given in GUI - "file_name_list" : additional information included in file name (can be empty string)
time_check: boolean
True: estimates runtime with reduced samples False: full calculation with saving data to files
return:
int : esimtated runtime (time_check == True) list : list of created files sorted by given cost criteria (time_check == False)
