In each step the LZSS algorithm sends either a character or a <position, Length> pair. Among these, perhaps character "e" appears more frequently than "x", and a <position, Length> pair of Length 3 might be commoner than one of Length 18, say. Thus, if we encode the more frequent in fewer bits and the less frequent in more bits, the total Length of the encoded text will be diminished. This consideration suggests that we use Huffman or arithmetic coding, preferably of adaptive kind, along with LZSS.

在程序中由playfair(char *s,int Length) 的實(shí)現(xiàn)加密和解密；解密原理與加密類似，只是加密過(guò)程的逆過(guò)程，它基于密文，采用同行取左邊，同列取下邊，其余取交叉的相反原理；在程序中用FLAG標(biāo)識(shí)區(qū)別，當(dāng)其值為1時(shí)，為加密過(guò)程；值為0時(shí)，為解密過(guò)程。

The Reed-Somolon code is specified by the finite field, the Length (Length <= 2^m-1), the number of redundant symbols (Length-k), and the initial zero of the code, init_zero, such that the zeros are: init_zero, init_zero+1, ..., init_zero+Length-k-1

Hard-decision decoding scheme Codeword Length (n) : 31 symbols. Message Length (k) : 19 symbols. Error correction capability (t) : 6 symbols One symbol represents 5 bit. Uses GF(2^5) with primitive polynomial p(x) = X^5 X^2 + 1 Generator polynomial, g(x) = a^15 a^21*X + a^6*X^2 + a^15*X^3 + a^25*X^4 + a^17*X^5 + a^18*X^6 + a^30*X^7 + a^20*X^8 + a^23*X^9 + a^27*X^10 + a^24*X^11 + X^12. Note: a = alpha, primitive element in GF(2^5) and a^i is root of g(x) for i = 19, 20, ..., 30. Uses Verilog description with synthesizable RTL modelling. Consists of 5 main blocks: SC (Syndrome Computation), KES (Key Equation Solver), CSEE (Chien Search and Error Evaluator), Controller and FIFO Register.

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.
