[City Labyrinth] San Francisco

Holy cow!!!
Awesome design!!
Very neat.

Precise in design and very pretty, but, I am afraid, impossible to traverse within any reasonable amount of time. I think these need to be driven, given the distances (with maybe some walking involved as well). San Francisco has many one way streets that need to be taken into consideration and it appears you are going straight through some areas that are impassable. The park you mark as "possible" IS possible to walk through--it is other areas that are questionable to impossible (for instance, playgrounds that are fenced off and going the wrong way on a one way street).

I have worked on a labyrinth for San Francisco myself (with some help from Ariock), which, not all perfect in design like yours, is definitely doable physically (taking into consideration one way streets, parks, etc.), if very long (approaching 90 miles). It is a 12-circuit labyrinth and covers most of the city.

has anyone tried using google maps' direction tweaking ability? I assume it takes into account one way streets, but being able to click and drag the route as much as necessary to create a labyrinth I'm guess would make things easier/quicker...

Are we sure that "non-walking" is allowed at all?

Nevertheless, the labyrinth could be shortend to a 3-circuit. This would lead naturally to a lower K. But we still know too little about the Ks and how much the sum of the 27 knots should be.

Here is the 12-circuit labyrinth I created within the boundaries of San Francisco. The purple areas are parts that need to be walked.

Seems pretty nice.

But I am not sure about the layout. All examples we know so far (Philadelphia + the labs on the transparent map from Monica, which probably have been used to draw city labyrinths) are symmetric.
So I would assume, that we need a symmetric design.

[Canzonett]

Symmetric to what degree? Perfect symmetry is almost impossible to achieve, especially in all the cities that don't follow a perfectly even rectangular street pattern.

Yes, it does not have to be perfect symmetric, but I think the overall pattern has to be almost a circle or a square, e.g. like the one I posted at the beginning of this thread - which seems unfortunately impossible to do regarding the information from people in SF.

I hope the 2 new artefacts will give some new clues about what we have to do in this task or some other valuable information...
