[mailto:[EMAIL PROTECTED] On Behalf Of Vijay M Sent: Thursday, 11 November 2004 12:07 To: [EMAIL PROTECTED] Subject: [ADVANCED-DOTNET] Random number generation. Hi all, I am trying to create a monte carlo code for some computational work in predicting the path of photons ! I have worked on .NET for the past two years but havent really pushed the random number generator to know a lot about it. A successful monte carlo code depends on a true random number generator and the efficieny of the generator is prime. I tried searching to determine any benchmarks as to whether the .NET Random object is truly random ! But there aren't that many articles in the net about it ( Maybe i was just blind ?! Feel free to throw some good links if you find ) I could have used Fortran to do it because for ages, people have been using Fortran to do Monte carlo code and it has been reliable. But i want to try it in .NET and hoped to settle this matter soon. If anyone has worked on cryptographic applications or monte carlo codes which depend solely on random numbers, help me out ! All right. All the ramble apart, the question is whether .NET can be used to create a successful Monte carlo code ?! If yes, then which class, System.Random or the System.Security.Cryptography.RandomNumberGenerator, do i use to get better results ? Also, i am planning to implement the algorithm as a multithreaded app. The online help specifies that both the classes are thread safe is declared static but instance variables are not ! Are there any issues in doing so ? Are there any best practices that can be followed while using Random numbers in a multithreaded app ?? These are some of the question that have stalled my work for now. Throw in your advice from experience. Would be glad to hear 'em ! Thanks.
