The aim of this paper is to develop an exact algorithm for the asymmetrical capacitated vehicle routing problem, i.e. the multiple travelling salesman proble...

BibTeX reference

This paper describes algorithmic approaches for dealing with fuzziness in some highly structured combinatorial problems. A general framework is described an...
