| 5 hours ago | comment | added | Tom Sirgedas | @RobPratt None of my solutions were contiguous. Surely 5 circles are enough by tinkering with #9, it's so close. | |
| 11 hours ago | comment | added | RobPratt | @WeatherVane For the "contiguous region" comment I meant that, whether or not you consider a one-point intersection sufficient for adjacency, all 12 maps in this answer have at least one disconnected (not path-connected) region. So the question is whether one of the other ~500 solutions has each region connected. | |
| 11 hours ago | comment | added | Weather Vane | @RobPratt I meant your "contiguous region" comment. I had to think about the corner crossing for a while and agree – even if the lines have no thickness they must cross in some state. | |
| 12 hours ago | comment | added | RobPratt | @WeatherVane If you're asking about my Four Corners comment, the solution violates the "exactly one circle" rule. | |
| 12 hours ago | comment | added | Weather Vane | @RobPratt do you mean that states must share a land border that is not a point? | |
| 12 hours ago | comment | added | RobPratt | What is the minimum if each circle must cover a contiguous region? | |
| 13 hours ago | comment | added | RobPratt | Another phony is #8 because of the alternating two-coloring of the Four Corners states. | |
| 18 hours ago | comment | added | Weather Vane | And #5 is dodgy too, with Montana cut by 2 circles, and Florida's border has not been crossed. I think a single good map would be better than an array of dubious ones. Please don't leave it to readers to filter them. Which one is your solution? | |
| 19 hours ago | comment | added | Toby Speight | I guess the "phony" is reveal spoiler number 6 of those, where reveal spoilerthe purple circle claims to pass exactly between two of the orange areas. | |
