WPC 2018, graphs

While analyzing the WPC result for my review series (starting with WPC 2018 review, part 1), I made a couple of pretty graphs, which I’d like to share here. To make these, I scraped the result PDF into a spreadsheet; I hope it’s useful to you.

To start with, a visualization of my scores per round, relative to the 10th best score. This is what I based my analysis on. A very flat Thursday, peak for the Paths round, Friday afternoon dip and then a strong finish.

A graph of the ratio of my score to the 10th best score, round by round.

Next a couple of graphs of how the positions developed over the course of the tournament. As a base-line for each of these, I chose the sum of n-th best scores per round, for a suitable n. First you can see just how much stronger Ken Endo is than anyone else, then that things were more exciting behind him than the first graph shows. And finally a top 20+ graph.

I’d love to see what else you can get out of the data!

WPC 2018 review, part 5

Welcome back, to the final episode packed with puzzles and drama. For the morning, we had the last two preliminary rounds on the schedule. By this time I knew where I was at: Around 14th place, which is a decent result for me relative to past performance. I managed to decide to be ok with it, particularly with not having come in to the competition in best shape.

WPC 2018 review, part 2

Second part of my review, with the afternoon of day one. I wrote about the morning in part 1. The afternoon was made up of three long rounds (60 minutes and twice 90 minutes), starting from 14:00. One of the really nice things this year was the consistent and relaxed schedule, with a regular long lunch break from a few minutes past 12 to 14, long enough breaks, and precise starting times. (Besides that first round of the WSC which started 3 minutes early, but… people were consistently on time after that!) I felt that things had been a bit packed and rushed the last three years, so this was a very welcome change to me.

WPC 2018 review, part 1

The 27th WPC is over. Like the last time I did this, there’ll be some criticism (as there would have been for the two past years), so let me thank the authors and organizers right away for the terrific job they did. I’ll go through the competition round by round again, covering rounds 1 through 3 (morning of day 1) in this post.

Like last time, I’ll compare to the 10th best score of each round. That value is reasonably unaffected by the out-of-this-world scores at the very top.

Championship report: Logic Masters 2016

I participated in the German Logic Masters on Saturday. Ulrich Voigt won the play-offs, ahead of Martin Merker, Philipp Weiß and Nils Miehe; I placed fifth. Puzzles and results should be published at the page linked above at some point. I’ll probably be posting some puzzles I made in preparation in the future; for now some thoughts on the tournament.
