Efficient Primal Heuristics for Mixed-Integer Linear Programs

Witryna15 lis 2011 · Abstract. This paper provides a survey of recent progress and software for solving convex Mixed Integer Nonlinear Programs (MINLP)s, where the objective and constraints are defined by convex functions and integrality restrictions are imposed on a subset of the decision variables. Convex MINLPs have received sustained attention in … WitrynaAssignation-sequencing models have played a critical role in the competitiveness of manufacturing companies since the mid-1950s. The historic and constant evolution of these models, from simple assignations to complex constrained formulations, shows the need for, and increased interest in, more robust models. Thus, this paper presents a … WitrynaThe pressing process is a part of the fabrication process of multi-layer printed circuit board (PCB) manufacturing. This paper presents the application of a new mixed-integer linear programming model to the short-term scheduling of the pressing process. The objective was to minimize the makespan.

Witryna14 sie 2024 · After a clever analysis of the problem at hand and of the acceptable simplifications in its definition, one tries to set up an effective mathematical programming (MP) model and to solve it by a general-purpose piece of software—often a mixed-integer linear programming (MIP) solver. WitrynaThe shortest linear program has been proved to be a NP-hard problem. In order to obtain the better approximate solution, a frequency-first heuristic method is proposed, which can optimize the number of XOR gates required by linear components while ensuring the stability of the algorithm.
