Question

Algorithm to find patterns

Asked by: rcoast

I need something that helps me find repeating patterns. I'm looking for some web references that have some theories on finding repetitive patterns in a large sample.

If I were looking for 10 byte patterns... it would be easy to find patterns. I simply read all the data and look for 10 byte patterns... but what I'm really looking for is X byte patterns... in an unlimited about of data.

Are there algorithms that do this?
