Web3 de out. de 2024 · TOMLAB /MINLP provides an advanced Matlab solution which includes four solvers developed by Roger Fletcher and Sven Leyffer at the University of Dundee. … WebThese MINLP solvers approximate the nonlinear convex function f(x) by a piecewise linear approximation, which is a sequence of linear cuts around the original function. In this way, the original MINLP is reduced to a sequence of MILP subproblems, each one with a more refined approximation to f ( x ) than previous MILPs, and yields a more optimal solution.
