Vinay Deolalikar made waves in August when his draft solution to a mathematical problem that haunts computer science hit the internet.
It's known as "P versus NP", and a correct solution is worth $1 million. Sadly for Deolalikar, of Hewlett-Packard Labs in Palo Alto, California, his work didn't check out. But the flurry of online activity surrounding the paper demonstrated a new way of doing mathematics - via blogs and wikis - and generated fresh excitement around the problem.
Formulated in 1971, P versus NP deals with the relationship between two classes of problems that are encountered by computers. P problems are relatively easy for computers to solve. But it can take an impracticably long time to solve NP problems, such as finding the shortest route between several cities - though it is easy to show whether a possible solution is correct.
