note Abigail-II Actually, a year is less than 2^55 nanoseconds. And I wouldn't call a set with 55 elements "huge". Beware of the power of exponentation. Your computer needs to speed up with a factor of 1000 to be able to increase your dataset with no more than 10 so that it will run in the same time.... <p> Abigail 227909 227921
