**February 2nd, 2015**. The deadline for submitting the write-up is **April 8th, 2015**.

Here are some suggested topics for the write-up. The write-up should include a clear intro- duction to the problem, some discussion of the solution highlighting particularly important tricks or techniques employed, and the impact the solution had (without hype). Please don’t just read wikipedia, if you are having hard time finding resources, come and talk to me about it.
