Path-Finding in Subway Networks

[Giancarlo]

Hello,
This subject has been in my head for long time now and i didn't know where to start.

I hope i can free my mind soon to focus on this (using a different machine) and the subway network of Milan (simplier).

Thanks for the docs you prepared and the algorithm reference. I'am going to try to understand them.

I remember some programs for hp48, very simple to understand how to go from A to B or Ato C in a kind of grid resembling your network.

Thanks for your work,

Giancarlo
