Johnson's algorithm consists of the following steps: 1. First, a new node q is added to the graph, connected by zero-weight edges to each of the other nodes. 2. Second, the Bellman–Ford algorithm is used, starting from the new vertex q, to find for each vertex v the minimum weight h(v) of a path from q to v. If this step detects a negative cycle, the algorithm is terminated.
