TaoGAAppSetGradientRoutine

Sets the gradient evaluation routine and gradient vector for use by the TAO_GA_APPLICATION routines.

Synopsis

#include "taoapp_ga.h" 
int TaoGAAppSetGradientRoutine(TAO_GA_APPLICATION gaapp, int (*grad)(TAO_GA_APPLICATION,GAVec,GAVec,void*),void *ctx)
Collective on TAO_GA_APPLICATION
