There are two potentially interesting things - * about this implementation: - * - * 1) The table is power-of-two sized. Prime sized tables are more - * traditional, but do not have a significant advantage over power-of-two - * sized table, especially when double hashing is not used for collision - * resolution. - * - * 2) The hash computation uses a table of random integers [Hanson97, - * pp. 39-41]. - * - * FUTURE ENHANCEMENTS - * - * With a table size of 512, the current implementation is sufficient for a - * few hundred keys. Since this is well above the expected size of the - * tables for which this implementation was designed, the implementation of - * dynamic hash tables was postponed until the need arises. A common (and - * naive) approach to dynamic hash table implementation simply creates a - * new hash table when necessary, rehashes all the data into the new table, - * and destroys the old table. The approach in [Larson88] is superior in - * two ways: 1) only a portion of the table is expanded when needed, - * distributing the expansion cost over several insertions, and 2) portions - * of the table can be locked, enabling a scalable thread-safe - * implementation. - * - * REFERENCES - * - * [Hanson97] David R.

[Knuth81, pp. 32-33] describes a shuffling technique - * that can eliminate this problem. - * - * If PRNGs are used for simulation, the period of the current - * implementation may be too short. [LE88] discusses methods of combining - * MLCGs to produce much longer periods, and suggests some alternative - * values for A and M. [LE90 and Sch92] also provide information on - * long-period PRNGs. - * - * REFERENCES - * - * [Knuth81] Donald E. Knuth. The Art of Computer Programming. Volume 2: - * Seminumerical Algorithms.
