That's a nice find. The recommended boost::mt19937 is the Mersenne Twister. It has an insane period accomplished with a 2500 byte "state". Even so, it runs about 4 times as fast as the improved Wichmann-Hill algorithm in their 2005 paper's estimation. The improved Wichmann-Hill may rank better on x64 though. -- You are receiving this mail because: You are on the CC list for the bug. You are the assignee for the bug.
