Instead of finding the longest common subsequence, let us try to determine the length of the LCS. Then tracking back to find the LCS. Consider a1a2…am and b1b2…bn. Case 1: am=bn. The LCS must contain am, we have to find the LCS of a1a2…am-1 and b1b2…bn-1. Case 2: am≠bn. Wehave to find the LCS of a1a2…am-1 and b1b2…bn, and a1a2…am and b b b b1b2…bn-1 Let A = a1 a2 … am and B = b1 b2 … bn Let Li j denote the length of the longest i,g g common subsequence of a1 a2 … ai and b1 b2 … bj. Li,j = Li-1,j-1 + 1 if ai=bj max{ L L } a≠b i-1,j, i,j-1 if ai≠j L0,0 = L0,j = Li,0 = 0 for 1≤i≤m, 1≤j≤n.

哈夫曼樹又稱最優二叉樹,是一種帶權路徑長度最短的二叉樹。所謂樹的帶權路徑長度,就是樹中所有的葉結點的權值乘上其到根結點的路徑長度(若根結點為0層,葉結點到根結點的路徑長度為葉結點的層數)。樹的帶權路徑長度記為WPL=(W1*L1+W2*L2+W3*L3+...+Wn*Ln),N個權值Wi(i=1,2,...n)構成一棵有N個葉結點的二叉樹,相應的葉結點的路徑長度為Li(i=1,2,...n)。可以證明哈夫曼樹的WPL是最小的。

VHDL implementation of the twofish cipher for 128,192 and 256 bit keys. The implementation is in library-like form All needed components up to, including the round/key schedule circuits are implemented, giving the flexibility to be combined in different architectures (iterative, rolled out/pipelined etc). Manual in English is included with more details about how to use the components and/or how to optimize some of them. All testbenches are provided (tables, variable key/text, ECB/CBC monte carlo) for 128, 192 and 256 bit key sizes, along with their respective vector files.
