I read a lot, that is how I know about most of the algorithms in my arsenal. But in this particular instance we dealt with Levenshtein Distance in a cryptography graduate class at Iowa State and I've used it in a couple other places other than Atomiq. I'd recommend reading as much as you can. Go out to wikipedia and start with the article on Donald Knuth, anything cool worth noting about algorithms isn't more than 2 or 3 links removed from his page.
