acm HDOJ 1051WoodenSticks Description: There is a pile of n wooden sticks. The length and weight of each stick are known in advance. The sticks are to be processed by a woodworking machine in one by one fashion. It needs some time, called setup time, for the machine to prepare processing a stick. The setup times are associated with cleaning operations and changing tools and shapes in the machine. The setup times of the woodworking machine are given as follows: (a) The setup time for the first wooden stick is 1 minute. (b) Right after processing a stick of length l and weight w , the machine will need no setup time for a stick of length l and weight w if l<=l and w<=w . Otherwise, it will need 1 minute for setup.

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。

CORDIC (Coordinate Rotation Digital Computer) is a method for computing elementary functions using minimal hardware such as shifts, adds/subs and compares. CORDIC works by rotating the coordinate system through constant angles until the angle is reduces to zero. The angle offsets are selected such that the operations on X and Y are only shifts and adds.

有一个魔王总是使用自己的一种非常精练而抽象的语言讲话,没有人能听得懂,但他的语言是可以逐步解释成人能听懂的语言,因为他的语言是由以下两种形式的规则由人的语言逐步抽象上去的: (1) α→β1β2…βm (2) (θδ1δ2…δn)→θδnθδn-1…θδ1θ 在这两种形式中,从左到右均表示解释。试写一个魔王语言的解释系统,用下述两条具体规则和上述规则形式(2)实现,把他的话解释成人能听得懂的话。 (1) B→tAdA (2) A→sae 设大写字母表示魔王语言的词汇;小写字母表示人的语言词汇;希腊字母表示可以用大写字母或小写字母代换的变量。魔王语言可含人的词汇。测试用例见题集p97。
