Greedy selection strategy

WebGreedy can be tricky Our greedy solution used the activity with the earliest finish time from all those activities that did not conflict with the activities already chosen. Other greedy approaches may not give optimum solutions to the problem, so we have to be clever in our choice of greedy strategy and prove that we get the optimum solution. A greedy algorithm is any algorithm that follows the problem-solving heuristic of making the locally optimal choice at each stage. In many problems, a greedy strategy does not produce an optimal solution, but a greedy heuristic can yield locally optimal solutions that approximate a globally optimal solution in … See more Greedy algorithms produce good solutions on some mathematical problems, but not on others. Most problems for which they work will have two properties: Greedy choice property We can make whatever choice … See more Greedy algorithms can be characterized as being 'short sighted', and also as 'non-recoverable'. They are ideal only for problems that have an 'optimal substructure'. Despite this, for many simple problems, the best-suited algorithms are … See more • The activity selection problem is characteristic of this class of problems, where the goal is to pick the maximum number of activities that do not clash with each other. • In the Macintosh computer game Crystal Quest the objective is to collect crystals, in a … See more • "Greedy algorithm", Encyclopedia of Mathematics, EMS Press, 2001 [1994] • Gift, Noah.
