3. The is a standard Bayes rule problem:
event B: bad guy, P(B) = 1/1e4
event -B: good guy P(-B) = 1-1/1e4
event A: alarm
P(A|B) = 99%
P(A|-B) = 1%
P(B|A) = P(BA)/P(A) = P(A|B)*P(B)/[P(A|B)*P(B) + P(A|-B)*P(-B)]
...

来自主题: Programming版 - why vb code faster than csharp???
above are C# codes and vb.net codes respectively(both compiled by vs.net 2008 Express):
In my laptop, results for speed testing:
Matlab:
ver 7.1: limit of array size overlimit for 1E4*1e4*1e1 size, has to
change to loop format 20x for loop
Total time: 38.01second
VB.net: total loop 1e9 (1 billion)
total time: 18.64 second
VSharp.net:
total time:21.5 second!!!
netSDK_CSC:
total time: 21.625 second!!!
Python 2.5:
10000x1000x10 loops with For-Loop (it's a very special one!)

柬埔寨 老挝 虽然有些山。 但在我党面前是小菜一碟。 公路铁路高压输电线水电站一
路修到底。
可以大幅改善柬埔寨老挝的生活水平。
同时开放一部分市场给老挝柬埔寨, 牢牢地绑在中华战车上。
