Pwrs Interior Point Solver.

Primal-dual interior point method for nonlinear programming. Solves min F(X) subject to nonlinear equalities/inequalities, linear constraints, and variable bounds.

Parameters:

  • f_fcn (callable or dict) – Objective callback [f, df, d2f] = f_fcn(x) or a problem dict containing the full solver inputs.

  • x0 (array_like, optional) – Initial point.

  • A (array_like, optional) – Linear constraints l <= A*x <= u.

  • l (array_like, optional) – Linear constraints l <= A*x <= u.

  • u (array_like, optional) – Linear constraints l <= A*x <= u.

  • xmin (array_like, optional) – Variable bounds.

  • xmax (array_like, optional) – Variable bounds.

  • gh_fcn (callable, optional) – Nonlinear constraint callback [h, g, dh, dg] = gh_fcn(x).

  • hess_fcn (callable, optional) – Lagrangian Hessian callback Lxx = hess_fcn(x, lam).

  • opt (dict, optional) – MIPS options dict controlling tolerances, linear solver choice, step control, and barrier parameters.

  • nargout (int, optional) – Number of outputs to emulate from the MATLAB interface.

Returns:

Returns (x, f, eflag, output, lambda_) or the leading subset requested by nargout.

Return type:

tuple or ndarray
