We consider the problem of rewriting a query efficiently using materialized views. In the context of information integration, this problem has received significant attention in th...
Searches that include both feasible and infeasible solutions have proved to be efficient algorithms for solving some scheduling problems. Researchers conjecture that these algorit...
