Accidentally Quadratic edit / delete

"I started this blog because over my career so far as a software engineer, I’ve kept personally running into software that was slow, and wondering why. And when I had time to point a profiler at them and debug the slowness, I would very often discover quadratic behavior, which could usually be drastically improved to linear, with just a little work."

How to Write a Spelling Corrector edit / delete

"The full details of an industrial-strength spell corrector are quite complex ... What I wanted to do here is to develop, in less than a page of code, a toy spelling corrector that achieves 80 or 90% accuracy at a processing speed of at least 10 words per second." Nice -- this'd be a good case study for our revamped algorithms module.

Bertrand Meyer's technology+ blog » Blog Archive » Lampsort edit / delete

"Leslie Lamport likes to use the example of non-recursive Quicksort. Independently of the methodological arguments, his version of the algorithm should be better known." This is a nice bit of proper computer science: the basic idea is to describe Quicksort in terms of sets of objects that have yet to be sorted (i.e. sort of the same way you usually describe pathfinding algorithms like A*).
