摘要

基于姚(A. Yao, J. Assoc.)的细胞探针计算模型,分析了优先队列操作的复杂性。第一版。28马赫,第3期(1981),615-628页)。开发了一种利用哈希函数族的方法,在满足大小约束的情况下,允许在恒定的最坏情况时间内实现优先级队列操作。估计计算秩函数所需的哈希函数族的最小大小,并将其与完美哈希所需的最小大小进行比较。

Hash functions for priority queues

The complexity of priority queue operations is analyzed with respect to the cell probe computational model of A. Yao (J. Assoc. Comput. Mach. 28, No. 3 (1981), 615–628). A method utilizing families of hash functions is developed which permits priority queue operations to be implemented in constant worst-case time provided that a size constraint is satisfied. The minimum necessary size of a family of hash functions for computing the rank function is estimated and contrasted with the minimum size required for perfect hashing.
