clarify "connected"

Mar 3, 2019 at 19:34 | comment | added | Frunobulax | @AndreasBlass Yes, you're right. I'll change that. | |
Mar 3, 2019 at 13:05 | comment | added | Andreas Blass | Conjecture: You meant the usual meaning of "connected", not "each square of each region must share at least one edge with at least one other square of the same region". The latter requires only that each connected component of a region contains at least two squares. | |

Mar 3, 2019 at 12:10 | comment | added | domotorp | For simplicity, suppose $n$ is odd. What about the special case of the problem when you have exactly $(\frac{n+1}2)^2$ voters? In this case the only way you can win is if you can create $\frac{n+1}2$ regions with exactly $\frac{n+1}2$ voters. I would guess that already this version is NP-complete. | |
