bool eval_f(Ipopt::Index n, const Ipopt::Number *x, bool new_x, Ipopt::Number &obj_value) override
bool eval_grad_f(Ipopt::Index n, const Ipopt::Number *x, bool new_x, Ipopt::Number *grad_f) override

See Ipopt::TNLP::eval_grad_f.

Note: Failure in eval_f (i.e. returning non-finite value or false) will make IpOpt try a new step, unless this happens at the starting point. However, if eval_f succeeds, but eval_grad_f fails, then IpOpt will terminate.

Parameters:

  • n –

  • x –

  • new_x –

  • grad_f –

Returns:
