Pup Matching: Model Formulations and Solution Approaches
(2002-01)We model Pup Matching, the logistics problem of matching or pairing semitrailers known as pups to cabs able to tow one or two pups simultaneously, as an NP-complete version of the Network Loading Problem (NLP). We examine ... -
A Simple But Effective Evolutionary Algorithm for Complicated Optimization Problems
(2002-01)A simple but effective evolutionary algorithm is proposed in this paper for solving complicated optimization problems. The new algorithm presents two hybridization operations incorporated with the conventional genetic ... -
