Algorithm Outline

This is just a simple outline of the path taken/functions called by the algorithm when executed.

in simple_ga.py unless otherwise specified

1. define functions in simple_ga
2. main_loop_exclusions()
3. process_parallel(all_ps, ncores)
4. map process_parameterset on all_ps
   a. IntitializationDB() (database.py)
   b. iterates over NUM_ITERATIONS, checking Stats_Database and adding to raw stats (simple_ga.py talking to database.py)
5. run_simulation (each iteration^)
   a. prep FitnessEvaluator (fe)
   b. set crossover, mutator, evaluator, initializator
   c. set selector, termination criteria, pop size, generations with GSimpleGA from pyevolve
6. evolve() (pyevolve — GSimpleGA.py)
   a. loop over evolutionary algorithm
