代入法的啟發(fā)示搜索
我的代碼實現(xiàn)是：按照自然語言各字母出現(xiàn)頻率的大小從高到低（已經(jīng)有人作國統(tǒng)計分析了）先生成一張字母出現(xiàn)頻率統(tǒng)計表（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)
，再對密文字母計算頻率，并按頻率從高到低生成一張輸入密文字母的統(tǒng)計表（B），通過兩張表的對應(yīng)關(guān)系，不斷用A中的字母去替換B中的字母，搜索不成功時就回退，在這里回朔是一個關(guān)鍵。

簡介 · · · · · ·
Multisensor data fusion is an emerging technology with important applications in both the military and civilian sectors, such as target recognition, robotics, medical diagnostics, and "smart" buildings. It draws on techniques from wide-ranging disciplines, including artificial intelligence, pattern recognition, and statistical estimation. This handbook is an up-to-date, comprehensive resource for data fusion system designers and researchers. Top experts in the field lead readers from a basic introduction and survey of data fusion technology to advanced mathematics and theory and to some very practical advice for systems implementers.
