5.1

View the full changelog here.

Breaking changes:

• The TournamentSelection operator now has an additional (non-optional) property numberOfOffspring which supersedes
  the old numOffspring Configuration property.
• EventDispatcher no longer contains methods for register EventListener definitions. The registration
  methods have been moved to EventRegistry.

Changes:

• Any components which make use of the experimental co-routine APIs have been marked with the @ExperimentalCoroutinesApi attribute.

• A new DiagnosticEvent has been exposed which allows introspection into the system. The majority of the built-in
  components have been updated to dispatch DiagnosticEvents for various actions. For example, to register a listener
  for trace events:

  EventRegistry.register(object : EventListener<DiagnosticEvent.Trace> {
    override fun handle(event: DiagnosticEvent.Trace) {
        // Do something with event
    }
  })

• Unit tests have been added for the following components (and there are more to come!):

  • Tournament selection operator
  • Recombination operator

Fixes:

• Address an incorrect typealias definition for MultipleOutputFitnessFunction (08fa90d)
• Refactor LinearCrossover operator and address a bug that caused program length to fall below the configured
  minimum program length (e46b135)
