Let G be a directed graph where c_e is the cost of arc e. If the nodes of G can be assigned feasible potentials then G has no negative dicycle.© BrainMass Inc. brainmass.com February 24, 2021, 2:19 pm ad1c9bdddf
Assume G has feasible potentials. Let y_v be the potential assigned to node v.
In particular then for any ...
A proof involving feasible potentials and dicycles is provided.
