✦ Synopsis

Fhe authors introduce refinements into the randomized pattern search method The randomized method of Lawrence and Stelghtz augments the ability of the method to adapt to direction An algorithm is derived that makes the method more adaptive in step size and incorporates penaltv terms to accommodate constraints The algorithm is robust and rehable and offers a scheme for obtaining ball-park estimates of a constrained global minimum Fletcher, R 73 2 'Fortran subroutines for minimization by quasi-Newton methods' Atomic Energy Res Est , Harwell, England (June 1972) 31 pp Two quasi-Newton subroutines are presented for minimizing a function F(x) of n variables x The gradient vector and the Hessian matrix are assumed to exist
