The trouble with tribbles is that their trilling seems to have a tranquilizing effect on the human nervous system. Fortunately, I am immune to this effect and I find this puzzle to be no tribble at all.

This may seem like it would be our hardest self-setting challenge yet. But the natural flow of traffic at these intersections allows just one or two lanes to go at a time; following these basic rules we can pass right through.

While we are now excellent at predicting the flow of traffic, it seems that it takes only a few incorrect bits to really cause more pileups. Fortunately we are getting phenomenal test data submissions to learn the ways of self-setting sudoku.

Straight roads are much easier for our current ASI, and we can always follow the numbers in front of / behind the others to keep in the right flow. Surely no unexpected scenarios will pop up in such a simplified situation.

Our testing was fine in a single country, like the US where Sudoku originated. But when we considered the rules of the road in Japan, and then the unusual spacing initially seen in Britain too, everything got messed up. Single systems are not useful. We’ll need to think about at least two, maybe three at a time to get to ASI.
