05 Oct 2009 Hill climbing optimization Constrained hill climbing optimization Author: Alexandros Leontitsis Karel

Be warned; this script does not properly respect the bounds. In certain cases, it will select a point just outside of the bounds, due to a bug in the code (bounds are only taken into account when the fitness function is being evaluated, not when adding a step to the current best point).
