  --cxProb F                  --mutProb F               --immigration F
  --tournament N              --stall N                 --targetFitness F
  --maxWallMs N               --maxEvaluations N        --expectedGenerations N

Units (generic):
  --perEvaluationMs F         --perGenerationOverheadMs F
  --perRunOverheadMs F        --perEvaluationCost F

Output:
  --json   print machine-readable JSON
