I was reading the other day about the Tube Challenge, where people attempt to visit all 270 stations on the London Underground in the quickest possible time. Apparently successful routes are a closely-guarded secret, which got me thinking about how difficult an optimisation problem it must be to find the best route.
A while back I heard about the Summer Data Challenge, hosted by my university. A number of datasets are available to download and analyse, and I chose to look at data on the selling price of properties in London over the past 5 years. I’ve assembled a number of plots here in order to examine this slightly cumbersome dataset more easily.
