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...
A greedy algorithm is an algorithm that follows the problem solving heuristic of making the locally optimal choice at each stage with the hope of finding a global optimum. In many problems, a greedy strategy does not in general produce an optimal solution, but nonetheless a greedy heuristic may...

algorithm at each step.In any of these models,one has to devise algorithms,called on-line algorithms, constructing feasible solu-tions whose values are as close as possible to optimal o,-line values, i.e. , to values of optimal solutions as-suming that the,nal instance is completely known...
run quickly, and use little memory, basically defining a good algorithm in contest terms. The only missing element from that list is correctness. If the greedy algorithm finds the correct answer, go for it, but don't get suckered into thinking the greedy solution will work for all problems...

贪心算法(Greedy Algorithm) 贪心算法 基本要素 贪心选择 常见应用场景 贪心算法(英语:greedy algorithm),又称贪婪算法,是一种在每一步选择中都采取在当前状态下最好或最优(即最有利)的选择,也就是说,不从整体最优上加以考虑,他所做出的是在某种意义上的局部最优解。比如在旅行推销员问题中,如果旅行员每次都...
