Hi

I am busy working on an optimisation program that makes extensive use of random
number (stochastic search). I have been using srand(time(NULL)) and rand() to
give random numbers in the range 0..1, which I then scale as required. I have
heard that rand() is not very good, so my questions are :
1. Is random() any better?
2. Are the libg++ Random classes better?

I need a normal distribution with zero mean, so 'better' refers to these
criteria.

Adios
