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.
WiiFuse is a FUSE filesystem module for Linux and Mac OS X. It will let you mount a Wii disc ISO and browse its contents, and it contains a server which may be run on the Wii so you can browse the contents of the Wii s internal filesystem.

Internationalization
The Java盲 2 platform provides internationalization features that let you separate culturally
dependent data from the application (internationalization) and adapt it to as many cultures as
needed (localization).
Generate Possion Dis.
step1:Generate a random number between [0,1]
step2:let u=F(x)=1-[(1/e)x]
step3:Slove x=1/F(u)
step4:Repeat Step1~Step3 by using different u,you can get x1,x2,x3,...,xn
step5:If the first packet was generated at time [0], than the
second packet will be generated at time [0+x1],The third packet will be generated at time [0+x1+x2],
and so on ….
Random-number generation
1.static method random from class Math
-Returns doubles in the range 0.0 <= x < 1.0
2.class Random from package java.util
-Can produce pseudorandom boolean, byte, float, double, int, long and Gaussian values
-Is seeded with the current time of day to generate different sequences of numbers each time the program executes
one of video tool Skype only in windows mobile5.0 more than running, but my task is to let it run Skype in WINCE only in windows mobile5.0 more than running, but my task is to let it run in WINCE . Leave no stone unturned when I can not get windows mobile, they thought would be needed for skype all library files to my WINCE, so perhaps will be able to run skype. 1. Used depend Show skype depends on which files. In fact, not many documents, I can remember only under the following: core.dllcommctr.dllaygeshell.dllhtmlview.dll In addition to htmlview.dll, the other documents in WINCE have (if your system does not, please IMAGE Canada on the corresponding module). Therefore, I find on the Internet htmlview.dll, the results really find
