Optimization of large join queries: combining heuristics and combinatorial techniques
1989
SIGMOD record
We investigate the use of heuristics in optimizing queries with a large number of joins. Examples of such heuristics are the augmentation and local improvement heuristics described in this paper and a heuristic proposed by Krishnamurthy et al. We also study the combination of these heuristics with two general combinatorial optimization techniques, iterative improvement and simulated annealing, that were studied in a previous paper. Several interesting combinations are experimentally compared.
