e.g. (row first, zero-based):
[(6, 3), (6, 4), (6, 5), (6, 6), (6, 7), (5, 7), (4, 7), (4, 8), (4, 9)]
[(6, 3), (7, 3), (7, 2), (7, 1), (6, 1), (6, 0), (6, 9), (5, 9), (4, 9)]

I don't think this puzzle is solvable (although I passed the check on Penpa). I have some cells with multiple shortest paths between them.

@copper.hat Maybe I'm being stupid but I don't see it. Do you have an algorithm in mind?

Say I have 2 equal sets of colored points, and I want to pair them up while minimizing the number of unique edges, where 2 edges are considered equal if they connect the same colors. Is this a hard problem?

And what if some estimates are deterministic (y_std=0)? Then weighted least-squares would blow up.

If I have a regression problem (e.g. with a neural network), where each y has an estimated uncertainty, does anyone have any idea what loss function I should use to learn the mapping from x -> (y_mean, y_std)? Weighted least squares with weights given by 1/variance seems reasonable for learning the mean, but I'm not sure about how to learn the variance.

Does anyone know how to get the tilde character on the UK Dvorak layout? It's shown as a second alternate key, but I've tried all the obvious combinations (ctrl, alt, shift, etc.) to no avail.

If someone posts a clever answer, then it should be fairly trivial to generate a shorter answer with the same n by e.g. taking the maximum run-time of the first answer and eliminating any programs which run longer. Perhaps you should instead use priority as a tie-breaker.

Only having 400 bytes available makes it hard to do anything interesting in a non-golfing language.

how would you e.g. convert 4 and 7 to binary and multiply the results?

I found a bug: If you double-cross then it is possible for bankid = self.guardbribes.pop() to raise the exception IndexError: pop from empty list

@quintopia Can you elaborate on how the tournament will be run? Will each match be all-against-all? Will all of your example programs play?

It would be much faster to keep the bot programs running continuously and pass arguments to stdin. This would also make it possible to preserve state between rounds.

@devRicher Too late. I'll delete the comments when the mistakes are fixed.
