Opt4JSetup

Companion object for the setup. Since Opt4J uses the GUICE framework for dependency injection, which does not seen to support the binding of anonymous inner classes, this object contains all problem-specific information that is required by the creator/decoder/evaluator classes.

To avoid bugs (race conditions etc.), the setup has a dedicated owner, i.e. in the current implementation Opt4J cannot be used to optimize multiple problems in parallel, only sequentially (this should not be too big a deal, as each objective function evaluation may be parallelized, and also the evaluation of different individuals).

type SESSLObjectiveFun[-X <: Objective] = (OptimizationParameters, X) ⇒ Unit

type SearchSpace = Seq[SearchSpaceDimension[_]]

The search space is defined as a sequence of search space dimensions.
