A parallel depth first search branch and bound algorithm for the quadratic assignment problem

We propose a new parallel Branch and Bound algorithm for the Quadratic Assignment Problem, which is a Combinatorial Optimization problem known to be very hard to solve exactly. An original method to distribute work to processors using the notion of Feeding Tree is presented. When adequately used, it allows to reduce memory contention and load unbalance. Therefore, a linear speed-up in the numbe...

A branch and bound algorithm for the generalized assignment problem

This paper describes what is termed the "generalized assignment problem". It is a generalization of the ordinary assignment problem of linear programming in which multiple assignments of tasks to agents are limited by some resource available to the agents. A branch and bound algorithm is developed that solves the generalized assignment problem by solving a series of binary knapsack problems to ...

An Exact Branch and Bound Algorithm for the General Quadratic Assignment Problem

This research is concerned with the development of an exact algorithm for a general quadratic assignment problem (QAP), of which the Koopmans-Beckmann formulation, in the context of an analysis of the location of economic activities or facilities, is a special case. The algorithm is based on the linearization of a general QAP of size n into a linear assignment problem of size n(n-l)/2. The obje...

A modified branch and bound algorithm for a vague flow-shop scheduling problem

Uncertainty plays a significant role in modeling and optimization of real world systems. Among uncertain approaches, fuzziness describes impreciseness while for ambiguity another definition is required. Vagueness is a probabilistic model of uncertainty being helpful to include ambiguity into modeling different processes especially in industrial systems. In this paper, a vague set based on dista...

A Honey Bee Algorithm To Solve Quadratic Assignment Problem

Assigning facilities to locations is one of the important problems, which significantly is influence in transportation cost reduction. In this study, we solve quadratic assignment problem (QAP), using a meta-heuristic algorithm with deterministic tasks and equality in facilities and location number. It should be noted that any facility must be assign to only one location. In this paper, first o...
