This new algorithm provides a fresh approach to produce a minimum spanning tree. A minimum spanning tree is a sub graph of any undirected weighted graph that gives the minimal cost valued edges to reach every node of any graph. The proposed algorithm is named as RAY algorithm for determining the minimum spanning tree. We named this new algorithm as RAY, as it gives a new ray of hope in the field of graphs that can be used as a better option for finding the minimum spanning tree of any undirected weighted graph with less duration of time as well as with an easy approach. RAY has less complexity with respect to time for finding the minimum spanning tree of any graph in comparison to other algorithms like prim's algorithm and Kruskal's algorithm which are mostly used to find a minimum spanning tree of the graph. RAY algorithm select any one node of the given graph as a root node and then it joins every edge connected to that node, which do not form any cycle in the graph. This process is repeated until we traverse each node of the graph and the edges those forms cycle during this process are stored separately. Now only these separately stored edges are traversed and we check in the graph for maximum weighted edge from the edges that are coming in the cycle which is formed due that particular separately stored edge. If there is any edge in the cycle which is greater in weigh than that of separately stored edge then we discarded maximum weighted edge and the new edge which we stored separately is taken into the minimum spanning tree. This same procedure is repeated for each edge that we stored separately. At the end of this procedure we get a tree which is the minimum spanning tree of the given graph by using RAY algorithm.Read More
