The solution delivered by the tabu search is partially destroyed by a randomised greedy procedure, and then the valid inequalities are used to guide the reconstruction of a complete solution. An application of the new method to the Job-Shop Scheduling problem is presented.application/pdfengL'accés als continguts d'aquest document queda condicionat a l'acceptació de les condicions d'ús establertes per la següent llicència Creative CommonsOptimised search heuristic combining valid inequalities and tabu searchinfo:eu-repo/semantics/workingPaperoptimised search heuristictabu searchgraspvalid inequalitiesjob shop schedulingBusiness Economics and Industrial OrganizationStatistics, Econometrics and Quantitative Methodsinfo:eu-repo/semantics/openAccess
