A while back Ovidiu Gheorghioiu told me this neat problem:

How would you build an efficient prime number generator?

Here's a neat problem I've seen again recently.

Given A, a set of n points in the plane, each point having integer coordinates. Come up with an algorithm that colors some of the points in the set red and the remaining points white in such a way that for any straight line L parallel to either one of the coordinate axes the difference (in absolute value) between the numbers of white point and red points on L is not greater than 1.

Here are a few problems that involve hill climbing or some form of local search. Feel free to suggest others and to discuss solutions.

Nice! I'm not a big fan of HDR, but this picture would benefit from some additional detail in the dark areas.
