PaPILO, a C++14-based software package, provides parallel presolve routines for (mixed integer) linear programming ... problem to those solvers and applies the postsolve step to the optimal solution.

Weighted marked graphs are convenient to model systems with bulk services and arrivals. We consider two problems of practical importance for this class of nets. The marking optimization problem ...

Abstract: The nonlinear magnetic properties of an iron core should be considered when topology optimization (TO) is applied to a realistic problem. However ... numerical instability of the sequential ...
