Greedy selection

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 Greedy algorithms typically (but not always) fail to find the globally optimal solution because they usually do not operate … See more • Mathematics portal • Best-first search • Epsilon-greedy strategy • Greedy algorithm for Egyptian fractions See more Greedy algorithms have a long history of study in combinatorial optimization and theoretical computer science.
