WebAug 19, 2014 · There is actually an algorithm which uses Dijkstra's algorithm in a negative path environment; it does so by removing all the negative edges and rebalancing the graph first. This algorithm is called 'Johnson's Algorithm'. The way it works is by adding a new node (lets say Q) which has 0 cost to traverse to every other node in the graph.
