Matching unmatched strings based on a unknown pattern

Alright guys, I really hurt my brain over this one and I'm curious if you guys can give me any pointers towards the right direction I should be taking. The situation is this: Lets say, I have a collection of strings (let it be clear that the pattern of this strings is unknown. For a fact, I can say that the string contain only signs fr...

Hi, I'm working on a cluster analysis program that takes a set of points S as an input and labels each point with that index of the cluster it belong to. I've implemented the DBScan and OPTICS algorithms and they both work as expected. However, the results of those algorithms can be very different depending on the initial values of MinP...
