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。

黑白点的匹配贪心算法 设平面上分布着n个白点和n个黑点,每个点用一对坐标(x, y)表示。一个黑点b=(xb,yb)支配一个白点w=(xw, yw)当且仅当xb>=xw和yb>=yw。若黑点b支配白点w,则黑点b和白点w可匹配(可形成一个匹配对)。在一个黑点最多只能与一个白点匹配,一个白点最多只能与一个黑点匹配的前提下,求n个白点和n个黑点的最大匹配对数。

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.
