Here are the packages with brief descriptions (if available):

localsolver	The classical version of LocalSolver is designed to solve large scale optimization problem in boolean, integer and continuous decisions. The model is described as a set of mathematical expressions that can be constrained or optimized
localsolverblackbox	LocalSolverBlackBox solves blackbox optimization problem where the objective function is unknown and costly to evaluate. The function can have boolean, integer or continuous decisions in a finite range
