Country : New Zealand | kiwijam posted @ 2017-10-06 9:19 AM 1) Four Winds Optimizer: Clarification - how many vertical segments are in the example solution, 6 or 10?
14) Doppelblock Optimizer: Are we minimizing the number of white cells touching a shaded cell (I count 14 in the example) or the number of edges between white and shaded cells (I count 30)?
In either case, the example solution is not unique. |

1 ) Consider it as 30 1-unit segments.
14 ) The former must be minimized. You're right about the example, we will get it fixed in version 2. Thanks! |

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? |

8) Tents Optimizer

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 |
