Issues

Random number generator

The project uses the built-in java.util.Random, which doesn't necessarily create random numbers of the highest quality (see link). This means that the simulated results may not be reliable (though they seem to be sensible). A better RNG needs to be implemented.

Algorithm speed

The algorithm is very slow, though still somewhat usable. A more effective algorithm has to be implemented. One obvious improvement is representing cards by bytes instead of Card-objects.
