This sounds cool, but how is this not a solution that's already been considered? It seems intuitively obvious to me that you can use a circuit simulator to solve this problem pretty quickly by assigning conductances to the edges of the graph. Modern circuit simulators are pretty good at converging on a solution in the presence of strong nonlinearities, so in principle you could even have edges that are more than simple conductances. (I have a CS degree, but I'm a circuit designer, so it's been a while since I've thought seriously about problems like this and I'm clearly not in touch with the state of the art. This question isn't snark, it's really a question.)
