- * DESCRIPTION
- *
- * This file contains a straightforward implementation of a fixed-sized
- * hash table using self-organizing linked lists [Knuth73, pp. 398-399] for
- * collision resolution.  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.

- * DESCRIPTION
- *
- * This file contains a simple, straightforward implementation of the Park
- * & Miller "Minimal Standard" PRNG [PM88, PMS93], which is a Lehmer
- * multiplicative linear congruential generator (MLCG) with a period of
- * 2^31-1.
- *
- * This implementation is intended to provide a reliable, portable PRNG
- * that is suitable for testing a hash table implementation and for
- * implementing skip lists.
- *
- * FUTURE ENHANCEMENTS
- *
- * If initial seeds are not selected randomly, two instances of the PRNG
- * can be correlated.  [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.
