TSSetCostIntegrand#
Sets the routine for evaluating the integral term in one or more cost functions
Synopsis#
#include <petscts.h>
PetscErrorCode TSSetCostIntegrand(TS ts, PetscInt numcost, Vec costintegral, PetscErrorCode (*rf)(TS ts, PetscReal t, Vec U, Vec F, void *ctx), PetscErrorCode (*drduf)(TS ts, PetscReal t, Vec U, Vec *dRdU, void *ctx), PetscErrorCode (*drdpf)(TS ts, PetscReal t, Vec U, Vec *dRdP, void *ctx), PetscBool fwd, void *ctx)
Logically Collective
Input Parameters#
numcost - number of gradients to be computed, this is the number of cost functions
costintegral - vector that stores the integral values
rf - routine for evaluating the integrand function
drduf - function that computes the gradients of the r with respect to u
drdpf - function that computes the gradients of the r with respect to p, can be
NULLif parametric sensitivity is not desired (mu=NULL)fwd - flag indicating whether to evaluate cost integral in the forward run or the adjoint run
ctx - [optional] user-defined context for private data for the function evaluation routine (may be
NULL)
Calling sequence of rf#
ts - the integrator
t - the time
U - the solution
F - the computed value of the function
ctx - the user context
Calling sequence of drduf#
ts - the integrator
t - the time
U - the solution
dRdU - the computed gradients of the r with respect to u
ctx - the user context
Calling sequence of drdpf#
ts - the integrator
t - the time
U - the solution
dRdP - the computed gradients of the r with respect to p
ctx - the user context
Notes#
For optimization there is usually a single cost function (numcost = 1). For sensitivities there may be multiple cost functions
Use TSCreateQuadratureTS() and TSForwardSetSensitivities() instead
