چکیده

Integer linear programming (ILP) problems occur frequently in many applications. In practice, alternative optima are useful since they allow the decision maker to choose from multiple solutions without experiencing any deterioration in the objective function. This study proposes a general integer cut to exclude the previous solution and presents an algorithm to identify all alternative optimal solutions of an ILP problem. Numerical examples in real applications are presented to demonstrate the usefulness of the proposed method. 2006 Elsevier B.V. All rights reserved.

Well-dispersed subsets of non-dominated solutions for MOMILP ‎problem

This paper uses the weighted L$_1-$norm to propose an algorithm for finding a well-dispersed subset of non-dominated solutions of multiple objective mixed integer linear programming problem. When all variables are integer it finds the whole set of efficient solutions. In each iteration of the proposed method only a mixed integer linear programming problem is solved and its optimal solutions gen...

On the integer max-linear programming problem

For a generic class of matrices we show that integer solutions to two-sided max-linear systems and programs can be found in polynomial time. For general matrices we adapt the existing methods for finding real solutions to obtain algorithms for finding integer solutions.

Flux Distribution in Bacillus subtilis: Inspection on Plurality of Optimal Solutions

Linear programming problems with alternate solutions are challenging due to the choice of multiple strategiesresulting in the same optimal value of the objective function. However, searching for these solutions is atedious task, especially when using mixed integer linear programming (MILP), as previously applied tometabolic models. Therefore, judgment on plurality of optimal m...

Finding Diverse Solutions of High Quality to Binary Integer Programs

Typical output from an optimization solver is a single optimal solution. At the same time, a set of high-quality and diverse solutions could be beneficial in a variety of contexts, for example problems involving imperfect information, or those for which the structure of high-quality solution vectors can reveal meaningful insights. In view of this, we discuss a new method to obtain multiple high...

Template Design under Demand Uncertainty by Integer Linear Local Search

Production planning under uncertain demands leads to optimisation problems that are hard both to model and to solve. We describe an integer linear model for a template design problem under uncertainty, and investigate its solution by a general-purpose local search algorithm for integer linear programs. Several such algorithms have previously been proposed as tools for solving large combinatoria...
