贪心算法，本章首先引入最优化的概念，然后介绍一种直观的问题求解方法：贪婪算法。最后，应用该算法给出货箱装船问题、背包问题、拓扑排序问题、二分覆盖问题、最短路径问题、最小代价生成树等问题的求解方案。-Greedy algorithm, this chapter first introduces the concept of optimization, then introduces an intuitive problem-solving methods: greedy algorithms. Finally, the algorithm to the shipping container loading problem, knapsack problem, topological sorting problem, the second sub-cover problem, the shortest path problem, minimum cost spanning tree programs for solving problems.
