Discussion of Problem 1115. Ships

Vladimir Yakovlev (USU) Problem 1115 "Ships". New tests? [13] // Problem 1115. Ships 28 Sep 2005 01:42
I know you all submit heuristics and get AC. In fact, tests are very easy to pass. I can change it.

I have new tests. These tests are really good. I think nobody's current solution get AC with these tests. But I have a solution and can't create a test that break it.

Do you want me to add this tests?

Dmitry 'Diman_YES' Kovalioff The problem has already been discussed (+) [1] // Problem 1115. Ships 24 Aug 2006 09:35
And a decision was made to create a new problem Timus-1394 "Ships. Version 2" which test set includes the hardest tests Vladimir Yakovlev could imagine. In fact even I did not solve this problem yet...
THX.
1394 is really hard problem(TLE24)...

Do u know some difficult tests or how to generate it?

I got ACed easily in 0.14s (not this ID!),
By adding a little Optimization.

TO ADMIN:
Did you use MaxFlow to Solve this Problem?
If you did, How could you solve the MaxFlow in a short Time?
