Fields

mutWeightRate :: Double: How often weights are mutated
newWeightRate :: Double: How often weights are replaced if mutated
pertAmount :: Double: Max amount of perturbation
weightRange :: Double: A new max is between negative this and positive this
addConnRate :: Double: How often new connections are made
addNodeRate :: Double: How often new nodes are added
largeSize :: Int: The minimum size for a species to be considered large
disableChance :: Double: How likely that a disabled parent results in a disabled child
distParams :: DistParams: Parameters for the distance function
dropTime :: Maybe Int: Drop a species if it doesn't improve for this long, and it hasn't hosted the most successful genome.
noCrossover :: Double: Percent of population that mutates without crossover
