slpctrl Posted December 6, 2007 Share Posted December 6, 2007 Is it possible to, using PHP, take an array of 3 or 4 digit numbers, and find some sort of real pattern in the numbers? I've been working on trying to get something semi reliable in finding a pattern in random 3 or 4 digit numbers, but can't seem to really get anything that seems remotely like any pattern. Any help would be appreciated. Quote Link to comment https://forums.phpfreaks.com/topic/80529-random-number-pattern/ Share on other sites More sharing options...
cooldude832 Posted December 6, 2007 Share Posted December 6, 2007 a pattern can really forced on to any set of integers so you can't say that exactly you could look at common series of numbers and then see if it matches one of those, but lets say I have {1,25,100,289} the pattern there is n^2 for a1 ((n*n)+(An-1))^2 for a >1 See the problem?

GingerRobot Posted December 6, 2007 Share Posted December 6, 2007 I've been working on trying to get something semi reliable in finding a pattern in random 3 or 4 digit numbers Surely, by definition, random numbers have no pattern? Im not sure what you're asking us to help you do. Perhaps if you provide some examples we might be able to help a bit more.

btherl Posted December 7, 2007 Share Posted December 7, 2007 You could also say that all random numbers have a pattern, if you allow arbitrarily complex patterns. For example, the pattern for 364,255,927,584 could be "364,255,927,584". So what counts as a pattern needs to be defined. For example, you may be looking for patterns where the numbers increase according to some simple rule (as in cooldude's example).

revraz Posted December 7, 2007 Share Posted December 7, 2007 By definition they wouldn't but computer generated random numbers sure do.
