WebDec 12, 2014 · MT19973 is a much higher quality random number generator (and for a Markov decision process you might need this quality). The only correct way of using rand (but its quality would still be inferior) is via sampling from a distribution whose size is a whole multiple of your actual distribution’s size, in a loop. That’s also less efficinet. WebDec 12, 2024 · A random number generator in C++ is used to generate a random number using a code.
