Search on the enumeration tree in the multiprocessor job-shop problem

P. 381-386.
Lazarev A. A., Carballo L., Vakhania N., Werner F.

We present an approach based on a two-stage ltration of the set of feasible solutions for the multiprocessor job-shop scheduling problem. On the rst stage we use extensive dominance relations, whereas on the second stage we use lower bounds. We show that several lower bounds can eciently be obtained and implemented.
