It is a well-known fact that there exists an ever increasing number of problems for which,despite the efforts of many inventive and persistent researchers, it seems virtually impossible to find efficient algorithms. In this situation, the theory of computational complexity may provide helpful...

Most scheduling problems are notoriously intractable, so the majority of algorithms for them are heuristic in nature. Priority rule-based methods still constitute the most important class of these heuristics. Of these, in turn, parameterized biased random sampling methods have attracted...
