Algorithm parameter keys of MOEA framework

Question

Using the withProperty method of the executing routine you can set several parameters of an algorithm i.e. for NSGA-II

NondominatedPopulation result = new Executor()
  .withProblem("UF1")
  .withAlgorithm("NSGAII")
  .withMaxEvaluations(10000)
  .withProperty("populationSize", 50)
  .withProperty("sbx.rate", 0.9)
  .withProperty("sbx.distributionIndex", 15.0)
  .run();

The documentation says

Each algorithm defines its own parameters. Refer to the API documentation for the exact parameter keys. Any parameters not explicitly defined using the withProperty methods will be set to their default values.

But I can not find these keys within NSGAII class. Can you give me a link to it.

Thanks in advance

Answer 1

I found them here: http://www.moeaframework.org/javadoc/org/moeaframework/algorithm/jmetal/JMetalAlgorithms.html

Man, those are not easy to find!

Your algorithm (NSGAII) in particular uses: NSGAII -> populationSize, maxEvaluations

Also ... totally agree that the NSGAII API documentation would've been a great place to put this information.
