Function Documentation

◆ load_CasADi_problem()

alpaqa::Problem load_CasADi_problem	(	const std::string &	filename,
		unsigned	n = `0`,
		unsigned	m = `0`,
		bool	second_order = `false`
	)

Load a problem generated by CasADi (without parameters).

Parameters

filename	Filename of the shared library to load the functions from.
n	Number of decision variables ( \( x \in \mathbb{R}^n \)).
m	Number of general constraints ( \( g(x) \in \mathbb{R}^m \)).
second_order	Load the additional functions required for second-order PANOC.

The file should contain functions with the names f, grad_f, g and grad_g. These functions evaluate the objective function, its gradient, the constraints, and the constraint gradient times a vector respecitvely. If second_order is true, additional functions hess_L and hess_L_prod should be provided to evaluate the Hessian of the Lagrangian and Hessian-vector products.

If any of the dimensions are zero, they are determined from the g function in the given file.

Exceptions

std::invalid_argument The dimensions of the loaded functions do not match.

Examples: CasADi/Rosenbrock/main.cpp.
