A few things, First, try this when creating your uniform_01 object, typedef boost::uniform_01<boost::mt19937> random_real; <--you typedef'ed it here. random_real actual_generator; actual_generator() <----to output numbers between 0 and 1. Two, don't use uniform_01. The uniform_real class works much better and defaults to between 0 and 1. Three, it looks like you are wanting random ints 0 and 1, not random real numbers between 0 and 1. For this have a look at the uniform_int or uniform_smallint class. They are probably what you are looking for. Hope this helps. Brian On 10/4/07, Jeffrey Holle <jeffreyholle@bellsouth.net> wrote:
I am at the point in my application where I must introduce randomness to a sort routine. Basically when 2 elements are equal, I need to create a 50% probability that they will be swapped.
What is the correct boost::random library resource to code this?
I've attempted to use uniform_01, by creating an instance of it with this type: typedef boost::uniform_01<boost::minstd_rand, double> rand_gen_t;
However, after getting it constructed as a class attribute, I find accessing it with: cout << (*pRand_gen++) << endl;
It produces numbers like 1 134784888 134784288 2 134784845 134784224 134785176 5 0 134784376 134785328 0.
What I want is a sequence like 0 1 0 1 0 1 0 0 0 1 1 1 1 0 1 0 1 that is sort of random.
