WebOct 8, 2012 · Relaxing an edge, (a concept you can find in other shortest-path algorithms as well) is trying to lower the cost of getting to a vertex by using another vertex. You are calculating the distances from a beginning vertex, say S, to all the other vertices. At some point, you have intermediate results -- current estimates.
