Overflow handling in hashing tables: A hybrid approach

摘要

The hybrid method of handling overflows in hashing tables, which incapsulates both open addressing and chaining, is presented. A simulation model which accounts for the effect of the loading order is developed in order to evaluate the average number of accesses and the average number of overflows under the hybrid method. Furthermore, two cost models are considered to compare the performance of the hybrid method with open addressing and chaining for hashing tables kept in main core and on secondary storage devices.
