class OptimisationProblem¶

Parent class(es)

NonlinearProblem

This is a base class for nonlinear optimisation problems which return the real-valued objective function $f(x)$ , its gradient $F(x) = f'(x)$ and its Hessian $J(x) = f''(x)$

OptimisationProblem()¶: Constructor

double f(const GenericVector &x) = 0¶: Compute the objective function $f(x)$

void form(GenericMatrix &A, GenericVector &b, const GenericVector &x)¶: Compute the Hessian $J(x)=f''(x)$ and the gradient $F(x)=f'(x)$

void F(GenericVector &b, const GenericVector &x) = 0¶: Compute the gradient $F(x) = f'(x)$

void J(GenericMatrix &A, const GenericVector &x) = 0¶: Compute the Hessian $J(x) = f''(x)$
