Mixed integer programming.

A mixed-integer programming (MIP) problem contains not only constraints but also integer restrictions. Integer restrictions divide the feasible region defined by constraints into multiple discontinuous feasible parts with different sizes. Several popular methods (e.g., rounding and truncation) have been proposed to deal with integer restrictions. Although … Mixed integer linear programming (MILP) is the state-of-the-art mathematical framework for optimization of energy systems. The capability of solving rather large problems that include time and space discretization is particularly relevant for planning the transition to a system where non-dispatchable energy sources are key.
