WebJan 9, 2016 · Typically, you would structure a “greedy stays ahead” argument in four steps: • Define Your Solution. Your algorithm will produce some object X and you will probably compare it against some optimal solution X*. Introduce some variables denoting your algorithm’s solution and the optimal solution. • Define Your Measure.
