You're getting close, Phoenix. Not there yet, though. First, a minor calculation error: 189 + 1890 + 27210 = 29289, not 29298 (I guess that's just a typo). Second, you are counting some identical routes several times. Exactly where that error occurs is difficult for me to say. If you have all your routes stored in a matrix, I suggest checking for duplicates (for example A, B, C, D = B, C, D, A or more likely C, D, A, B).

My code for some reason malfunctioned with some numbers. I had some ABCC.
I removed them and recounted.
189 + 1890 + 26897=28976

When two ports sell the same good, I make sure that is always port 1 and 3, to avoid duplicates. The only situation where I let port 2 and 4 sell the same good, is when port 1 and 3 ALSO does so (segment 3).
...
The reason for distingusihing between segment 2 and 3 was therefore becasuse I knew I had to divide by different numbers.

This is an interesting strategy to eliminate those duplicates. I like it.
I have also been separating the different types of duplication- absolutely needed to divide by the correct number.

Shaydo and I are approaching it a bit more empirically. We're each creating our own complete list without duplicates and hopefully our lists will agree. I'm sure we will choose different duplicates to keep so checking the lists against each other will take its own script that may run for a few hours.

can you give us a full list of the duplicates?

I KNOW I got the correct answer, but I have a philosophical issue: Should I hope dungeness also get's the correct answer, or not? If he DOES get the correct answer, then I assume I would be eligible for the 15M reward. If, however, he does NOT get it correct, I should actually be eligible for the 30M reward, since he then got a wrong answer and I have proved that it is wrong (since I've proved what's right). However, since he is obviously the "judge" of who he wants to give a reward, how would I get the reward for proving him wrong, if he did not understand my proof? Tricky, tricky...

I tried to attach an excel sheet with all routes possible but excel is not an accepted format. Anyone know which ones are accepted?

Why not put it up on google drive or something?

The Great Impasse Metaphysical Prodogeny : its a key element of advanced gaming studies and has cause many a nervous breakdown : its is credited with the auto-destruction of the original Deep Thought super-computer and has led to the common shorthand term for total failure :'gimp-ed out', as in 'Hey dude, he just gimped out when he saw the question papers!'

of course YOU think you're right. the question is are you actually right? we all think our numbers are right too!

I think my numbers are wrong, and I know I am right!
