Combat Optimization and Analysis Program - COAP. Volume II. Program User;s Manual.

Abstract

COAP is a program for the simulation and optimization of combative and cooperative two-vehicle flight paths. It includes single vehicle flight path problem capability as a subcase. Considerable emphasis is placed on the use of modern optimization. The program has the ability to perform trajectory optimization by the variational steepest-descent method including search for optimal initial conditions; search for optimal arc (stage) lengths; constraints defined at terminal point, intermediate corners (stage points), or along the path; and optimum parameter (design variable) values. The program can solve two system (vehicle) problems with or without reacting feedback from the second system (vehicle). Alternatively, the program may be used to apply the direct multivariable search approach to trajectory optimization. A variety of multivariable search algorithms are available in this mode including elemental perturbation (one parameter at a time); organized first- and second-order methods, and randomized methods. A method of solution for problems exhibiting multiple extremals and a procedure for the location of saddle points is also included. (Author)
