| 术语 | hashing algorithm |
| 释义 | hashing algorithm 散列算法;［杂乱演算法］ An algorithm used in constructing and maintaining hashed random files by which record keys are modified to produce their addresses in the address space of the file (on magnetic disc). A variety of algorithms are used, either singly or in combination; for example, folding, truncation, dividing by a constant and taking either the quotient or remainder, changing the radix, and squaring. Extraction (by mask) is often used to obtain an address of the required number of digits and various methods are used to select an output that is within the address space of the file. 用于建立和维护散列随机文件的一种算法,通过它修改记录关键字,以便产生文件地址空间中(在磁盘上)的相应地址。这类算法或是 单个的或是组合的,例如折叠、截断、除以常数并取其商或余数、改变基数及求平方。 经常用掩码方法析取所要求数位的地址,并用各种方法选择文件地址空间中的一个输出。 |
