That's an interesting answer! Your final layout looked oddly familiar to me, and it finally occurred to me: The problem of finding a skeleton puzzle was very similar to finding an optimal layout for a sugarcane farm in Minecraft, that my high school friends and I experimented with years ago. Each square of sugarcane needs to be connected to at least one square of water, and the most efficient farm is the one requiring the least amount of space for water. https://i.imgur.com/T5yh9.jpg https://i.imgur.com/T5yh9.jpg
