Description: 代入法的启发示搜索
我的代码实现是：按照自然语言各字母出现频率的大小从高到低（已经有人作国统计分析了）先生成一张字母出现频率统计表（A）--------(e),(t,a,o,i,n,s,h,r),(d,l),(c,u,m,w,f,g,y,p,b),(v,k,j,x,q,z)
，再对密文字母计算频率，并按频率从高到低生成一张输入密文字母的统计表（B），通过两张表的对应关系，不断用A中的字母去替换B中的字母，搜索不成功时就回退，在这里回朔是一个关键。
-generation into a search of inspiration I said a code is : According to the Natural Language alphabet frequency of the size of precedence (has been for the State Statistical Analysis), Mr. into an alphabet frequency tables (A )--------( e), (t, a, o, i, n, s, h r), (d, l), (c, u, m, w, f, g, y, p, b), (v, k, j, x, q, z), again close to the mother language calculated frequency and frequency input precedence generate a secret letter to the mother TAB (B), Table 2 by the corresponding relations, use of the letters A to B to replace the letters of the alphabet, when unsuccessful search regression, Here is a retrospective key.

的引用次数。Java 虚拟机利用预处理模块所收集的信息,判定各块程序的执行频率,对高频部分进行内联、寄存
器分配等优化处理。本文还讨论了Java 虚拟机实现中的若干事项。-Code optimization is to improve an important means of the Java virtual machine execution speed. This paper presents an optimization method based on the preprocessed code. Pre-processing module with embedded Java virtual machine to work in parallel, its marked basic block, cycle structure, and collect the data flow analysis method, the number of citations of each variable. Java virtual machine to use the information collected by the pre-processing module to determine the execution frequency of each block on the high-frequency part of inlining, register allocation optimization. The article also discusses a number of issues in the implementation of the Java Virtual Machine. Platform: |
