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。

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

The Game: Make the snake grow longer by directing it to the food. Extra bonus points are given from hearts, eat them as fast as possible as amount of bonus points decreases with time. Higher level gives more points for the food but will also make it tougher to steer a long snake as speed increaces. Five different mazes as well as play w/o maze are possible.

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.
