  abstract =     "The software package SNOBFIT for bound constrained (and soft constrained) noisy optimization
                 of an expensive objective function is described. It combines global and local search by branching
                 and local fits. The program is made robust and flexible for practical use by allowing for hidden
                 constraints, batch function evaluations, change of search regions, etc.",
