本題采用的計(jì)算方法為:矩陣的 分解和Cholesky分解。根據(jù)Gauss消去法的的矩陣意義,可以將矩陣A分解為一個(gè)單位下三角矩陣與一個(gè)上三角矩陣的乘積即:即矩陣的LU分解A=LU,進(jìn)而可以分解為: 的形式。當(dāng)A為對(duì)稱矩陣時(shí),A可分解為: 的形式。

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(duì)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(duì)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(shí)就回退,在這里回朔是一個(gè)關(guān)鍵。

黑白點(diǎn)的匹配貪心算法 設(shè)平面上分布著n個(gè)白點(diǎn)和n個(gè)黑點(diǎn),每個(gè)點(diǎn)用一對(duì)坐標(biāo)(x, y)表示。一個(gè)黑點(diǎn)b=(xb,yb)支配一個(gè)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(gè)匹配對(duì))。在一個(gè)黑點(diǎn)最多只能與一個(gè)白點(diǎn)匹配,一個(gè)白點(diǎn)最多只能與一個(gè)黑點(diǎn)匹配的前提下,求n個(gè)白點(diǎn)和n個(gè)黑點(diǎn)的最大匹配對(duì)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.
