I need to do some statistical work in C++, so I am trying to use the TR1 extensions. I am using g++ Debian 4.3.4-1. To become familiar with the distributions, I found various example code to run. I get some of the samples to run, and others go off into 100% cpu never to return. (For the Debian implementation, I have to change std::tr1:: to std::) The following sample routines work as advertised except for differences in expected output: Linear Congruential http://msdn.microsoft.com/en-us/library/bb981982.aspx g++ output matches web page Mersenne Twister http://msdn.microsoft.com/en-us/library/bb982912.aspx g++ output matches web page Bernoulli Distribution http://msdn.microsoft.com/en-us/library/bb981930.aspx g++ output matches web page Normal Distribution http://msdn.microsoft.com/en-us/library/bb982450.aspx g++ output DOES NOT match web page Exponential Distribution http://msdn.microsoft.com/en-us/library/bb982022.aspx g++ output DOES NOT match web page The following sample routines never return from the test program: Poisson Distribution http://msdn.microsoft.com/en-us/library/bb982995.aspx never returns Binomial Distribution http://msdn.microsoft.com/en-us/library/bb982497.aspx never returns Testing C++ TR1 random number generation http://www.johndcook.com/test_TR1_random.html never returns Could someone tell me what might be wrong? Is the Debian TR1 support not working correclty? Is the sample code invalid? Would Boost work better on this sample code? Is TR1 support not ready for prime time? Thanks! Lester
