WebGreedy Algorithms are similar to dynamic programming in the sense that they are both tools for optimization. However, greedy algorithms look for locally optimum solutions or in other words, a greedy choice, in the hopes of finding a global optimum. WebIt falls under a class of algorithms called greedy algorithms that find the local optimum in the hopes of finding a global optimum.

WebA spanning tree is a sub-graph of an undirected connected graph, which includes all the vertices of the graph with a minimum possible number of edges. If a vertex is missed, then it is not a spanning tree. The edges may or may not have weights assigned to them. http://duoduokou.com/algorithm/50867821092277819463.html
