The Internet Problem Solving Contest has just started.
The Internet Problem Solving Contest (IPSC) is an online contest for teams consisting of up to three people. Several problems will be published at the beginning of the competition. Each problem consists of a problem description and two input data sets. To solve a problem you will have to compute correct output data for the given input data sets. Usually this means that you will write a program that solves the problem, but you may produce the output by hand or in any other way.
So it’s very computer-sciencey, in the vein of Project Euler, but there’s some maths required; for example, the “matrix nightmare” problem involves a pretty hefty bit of linear algebra.
