Graphs with negative edge costs, but no negative cost cycle, can use Bellman-Ford's shortest path algorithm. Topological sorting is used for scheduling a sequence of tasks based on their dependencies. A graph with a cycle cannot have a topological sort. In a complete graph all vertices have a degree equal to |V|
