Fixed set search applied to the multi-objective minimum weighted vertex cover problem

Jovanovic, Raka; Sanfilippo, Antonio P.; Voß, Stefan - In: Journal of Heuristics 28 (2022) 4, pp. 481-508

Search Procedure (GRASP). In recent publications, its efficiency has been shown on different types of combinatorial … Problem (MWVCP). In this work, a simple and effective bi-objective GRASP algorithm for the MWVCP is developed in the first … stage. One important characteristic of the proposed GRASP is that it avoids the use of weighted sums of objective functions …

Multi-objective evolutionary search strategies in constraint programming

Bennetto, Robert; Vuuren, Jan van - In: Operations research perspectives 8 (2021), pp. 1-15

It has been shown that evolutionary algorithms are able to construct suitable search strategies for classes of Constraint Satisfaction Problems (CSPs) in Constraint Programming. This paper is an explanation of the use of multi-objective optimisation in contrast to simple additive weighting...
