I didn’t add last week’s Classic to this blog, but I did produce a pretty graph in Jupyter from which you can read the right answer (in either graph, the point on the x-axis where the orange four-post line first exceeds the blue three-post line.)
This week’s Express is not difficult, but I did find the answer a little surprising.
I’m doing this, with my girlfriend. I have bought a place in the UK before, but other people handled all of the paperwork in that case. So my initial expectations were for something like the UK system, but the reality was a little different. We haven’t finished yet, but this post is an outline of the important differences I saw.
I did this one analytically and by brute force simulation, and got the same answer with both methods. It’s in a github gist.
