The C# code had a serious problem in its implementation. It selected a random position from the *entire* array on each loop. This is a serious problem as it leads to a non-uniform distribution of outcomes, thereby ruining the purpose of the algorithm. Wikipedia has a nice description of the problem [http://en.wikipedia.org/wiki/Fisher%E2%80%93Yates_shuffle#Implementation_errors here]. |
