OPTPACK - OPTimisation PACKage

Fortran optimisation package containing routines and shell scripts for parallel global multi-start optimisation, more specifically simulation based optimisaion. The problem is fitting mechanical behaviour of materials from FE simulation of a range of tests, initially buckling of cylindrical rods. The objective function is based on sum of squares of the residuals between experimental and FE load/displacement data. OPTPACK is distributed under BSD license. See LICENSE file.
