A Fortran Implementation of a Sequential Quadratic Programming Algorithm for Heuristic Global Optimization
Version 3.9 (2012)
Successively, local minima are cut off by introducing additional constraints. Some safeguards are needed to stabilize the algorithm, since very little is usually known about the distribution of local minima. It is tried to keep away an iteration sequence from known local minima.
NLPQLG is implemented within the structural mechanical optimization system LAGRANGE at EADS to solve large structural design optimization problems.
