# Some sample aditional parameters for steady-state evolution,
# beyond what's provided in, say, simple/simple.params
#

# ec.Evolve
# ==============================

# simple generational evolution
state =         ec.steadystate.SteadyStateEvolutionState

# We can EITHER say to run for N evaluations of subpopulation 0
# (evaluations in other subpopulations are not counted) like this:
# evaluations = 50000

# ... or we can say to run for N generations, where a generation
# is equal to the size of subpopulation 0.  After the initial population
# is evaluated, only one additional individual is evaluated each time
# generations = 50

# threads should be 1 each
evalthreads =         1
breedthreads =        1

# ec.EvolutionState
# ==============================

# We'll use a SimpleExchanger
exch =          ec.simple.SimpleExchanger

# We MUST use a SteadyStateBreeder and SteadyStateEvaluator
breed =         ec.steadystate.SteadyStateBreeder
eval =          ec.steadystate.SteadyStateEvaluator

# We must specify a deselector for each subpopulation.  Here is random
# deselection for subpopulation 0.
steady.deselector.0 =     ec.select.TournamentSelection
steady.deselector.0.size =    1
steady.deselector.0.pick-worst =  true

# Traditionally, steady-state GAs try hard not to produce duplicates.
steady.duplicate-retries =    100
