Branch and Bound Algorithm for a Discrete Multilevel Linear Fractional Programming Problem
Operations Research and Decisions, 2018 An algorithm is proposed to find an integer solution for bilevel linear fractional programming problem with discrete variables. The method develops a cut that removes the integer solutions which are not bilevel feasible.

Branch-and-cut solution approach for multilevel mixed integer linear programming problems
EURO Journal on Computational Optimization, 2023 A multilevel programming problem is an optimization problem that involves multiple decision makers, whose decisions are made in a sequential (or hierarchical) order. If all objective functions and constraints are linear and some decision variables in any

THE RAY-METHOD: THEORETICAL BACKGROUND AND COMPUTATIONAL RESULTS
Croatian Operational Research Review, 2012 In our talk we present an algorithm for determining initial bound for the Branch and Bound (B&B) method. The idea of the algorithm is based on the use of the "ray" introduced in the "ray-method" developed for solving integer programming problems [13 ...

Product Distribution Optimization in Food SMEs with Integer Linear Programming
MATEC Web of Conferences, 2018 Efficient product distribution is a key driver of the overall profitability of a company. The high cost of product distribution in food SMEs is caused by the absence of a proper distribution cost calculation to obtain optimal distribution decisions. This

Bit Representation Can Improve SDP Relaxations of Mixed-Integer Quadratic Programs [PDF]
, 2018 A standard trick in integer programming is to replace bounded integer variables with binary variables, using a bit representation. In a previous paper, we showed that this process can be used to improve linear programming relaxations of mixed-integer ...
