When shuffling large arrays, how much time can be attributed to random number generation?
It is well known that contemporary computers don’t like to randomly access data in an unpredictible manner in memory. However, not all forms of random accesses are equally harmful. To randomly shuffle an array, the textbook algorithm, often attributed to Knuth, is simple enough: void swap(int... Read more
