The use of a non-conventional linear programming technique, involving a piecewise differentiable penalty function minimization, is presented in this paper in connection with power system Constrained ...

The solver is particularly useful when the problem to be solved is ill-conditioned. This is often the case, for example, when the linear system arises from a discretization of a ...

HiGHS is a high performance serial and parallel solver for large scale sparse linear optimization problems of the form min 1 2 x T Q x + c T x s.t. L ≤ A x ≤ U ; l ≤ x ≤ u where Q must be positive ...

Unit commitment problems can be solved more efficiently with mixed integer linear programming solvers when more preferred hyperparameters are configured. We propose a learning approach to configure ...
