Cayley graph search with Claude Code: what puzzle competitions look like in 2026 Over the last couple of months, I worked on two Kaggle competitions in the CayleyPy series: IHES Picture Cube and Megaminx. Both are combinatorial puzzle solvers, and they can be reformulated as a search in an...
In this document, I will briefly explain my way of solving the VSB Power Line Fault Detection competition. The metric used in that competition was Matthews correlation coefficient (MCC) between the predicted and the observed response. My final score was 0.58655; the best score was 0.71899 (a...
For those who don't know Kaggle Competitions: they are machine-learning competitions where multiple teams (or individuals) compete for the best score. My problem is shown in the following three screenshots of the final ranking (the leaderboard) for three Kaggle competitions: Predicting...
