8) Tents Optimizer
What is the definition of "chain"?
1. Can a chain have any branches?
2. Can any loops be formed? If so, how do we count its length?


A Chain is a single continuous path without crossings and branches (these structures can happen but won't be included in the count). The path must contain a tree or a tent in every cell along it. It can form a loop. The length is always counted as number of cells containing tents + number of cells containing trees along the path.

We will incorporate some of this into version 2. Thanks!

I assume a branch on a loop could be counted as you could draw from it to the loop and follow the loop around, making a single path that never backtracks.

A chain can't, but a tree can, I suppose

Will the optimization requirements in the contest all be the same as the ones in the examples?
