- 12:27, 17 June 2024 Example code - Prime numbers optimization (hist | edit) [9,983 bytes] WikiSysop (talk | contribs) (Created page with "This is going to be a long, but quite instructive rant about various optimization ideas and techniques.<br> Let us start with my "classic" prime number generator. The idea is to see how long time is takes to find/generate the primes between 0 and 10 000 000 and use that as a measure for performance. We know that primes are integers which can only be divided by 1 and the primes itself. Therefore it is an obvious idea to evaluate if a number is a prime by starting to divi...")
