Greedy algorithms are algorithms which follow the problem solving meta-heuristic of making the locally optimum choice at each stage with the hope of finding the global optimum. For instance, applying the greedy strategy to the travelling salesman problem yields the following algorithm: "At each stage visit the unvisited city nearest to the current city".†
