We present the long-awaited new, fresh, and crispy design of SPOJ! It's taken us a while to get here since 2004, but hey, it looks good - doesn't it? There's now a new feature for tagging and grading problems. We are also working to make SPOJ as mobile-friendly as possible. Stay tuned, because there are many more surprises to come!

Goodbye Pyramid

During the last six months, we have been gradually migrating our "checkers" (servers which execute submissions) from old to new machines. The procedure required some care since the new machines have significantly greater processing power. The main difficulty was adjusting the time limits for problems: in general, the new machines seemed to be more "tolerant" of slow solutions than the old ones. Over the 10 years of existence of SPOJ, our great community has produced over 13.5 million submissions (10 million of which on the old checkers) and we didn't want to rejudge all of them. So, we designed an algorithm for recalculating submission running times by interpolation. Data for reliable interpolation came from a real rejudge of a representative sample of 5% of the submissions, i.e., 511,000 submissions have been rejudged over the past six months. At the end, we changed the time limits of test cases keeping them in relation to running times of solutions.
