public class ImprovementAlgoBuilder
extends TwoStageAlgoBuilder<BoundConstrainedProblem,ImprovementDiviner,AbstractOptimizer<BoundConstrainedProblem>>

A two-stage optimization algorithm based on some measure of prospective improvement: typical examples include expected improvement, probability of improvement, etc. Modifies the update() method to set the a design target at each iteration, usually the best design found so far.
