[EM] Directional Resistance

[Jobst Heitzig]

Dear Forest,

nice idea, but I'm almost sure it will not be cloneproof. Consider three 
options x,y,z. Then the circuit resistance from x to z is 
  1 / (1/Rxz + 1/(Rxy+Ryz)).
When we add a y-clone y', it seems we get
  1 / (1/Rxz + 1/(Rxy+Ryz) + 1/(Rxy'+Ry'z))
which is smaller. Although all other pairwise circuit resistances will 
also decrease, it seems that this will not happen in such a coordinated 
way that the winner is preserved. 

Yours, Jobst
