It looks pretty simple to transform the uniform distribution to the geometric distribution. The formula for its cdf is pretty simple: cdf(p,n) = (1-p)**(n-1)*p For fixed p, if the cdf is c, we get (unless I made an error), n = log(c, 1-p) - 1 So choose a uniform point c in the unit interval, run it through that formula, and round up to the nearest integer. See http://en.wikipedia.org/wiki/Geometric_distribution for more about the distribution. -- http://mail.python.org/mailman/listinfo/python-list
