Abstract: A direct search penalty function procedure is described for treating a rather general mathematical programming form of the optimal design problem. A rotating coordinate modification of the pattern ...

Abstract: Two mathematical programming procedures for treating nonlinear problems involving mixed variables are presented. One involves a relatively simple concept. First an optimum is located treating all ...

Abstract: An improved, nonlinear, constrained algorithm is presented, coupling a rotating coordinate pattern search with a feasible direction finding procedure used at points of pattern search termination. ...

Abstract: A new procedure for numerical optimization of constrained nonlinear problems is described. The method makes use of an efficient “Boundary Tracking” strategy to move on the constraint surfaces. ...
