代入法的啟發(fā)示搜索 我的代碼實(shí)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(jì)分析了）先生成一張字母出現(xiàn)頻率統(tǒng)計(jì)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(jì)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(jì)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。

黑白點(diǎn)的匹配貪心算法 設(shè)平面上分布著n個白點(diǎn)和n個黑點(diǎn)，每個點(diǎn)用一對坐標(biāo)（x, y）表示。一個黑點(diǎn)b=（xb,yb）支配一個白點(diǎn)w=(xw, yw)當(dāng)且僅當(dāng)xb>=xw和yb>=yw。若黑點(diǎn)b支配白點(diǎn)w，則黑點(diǎn)b和白點(diǎn)w可匹配（可形成一個匹配對）。在一個黑點(diǎn)最多只能與一個白點(diǎn)匹配，一個白點(diǎn)最多只能與一個黑點(diǎn)匹配的前提下，求n個白點(diǎn)和n個黑點(diǎn)的最大匹配對數(shù)。

EDB (Evan s Debugger) is a QT4 based binary mode debugger with the goal of having usability on par with OllyDbg. It uses a plugin architecture, so adding new features can be done with ease. The current release is for Linux, but future releases will target more platforms. Release focus: Major feature enhancements Changes: A new disassembly engine. A bug that could cause crashing was fixed. There is a new flags breakdown in the register view, an environment view plugin, and improved analysis (including a good speed increase). A bug in QT where disabled events could be triggered has been worked around.
