1 camerini s algorithm undirected graphs 1.1 pseudocode 1.2 running time 1.3 example camerini s algorithm undirected graphs camerini proposed algorithm used obtain minimum bottleneck spanning tree (mbst) in given undirected, connected, edge-weighted graph in 1978. half divides edges 2 sets. weights of edges in 1 set no more in other. if spanning tree exists in subgraph composed solely edges in smaller edges set, computes mbst in subgraph, mbst of subgraph mbst of original graph. if spanning tree not exist, combines each disconnected component new super vertex, computes mbst in graph formed these super vertices , edges in larger edges set. forest in each disconnected component part of mbst in original graph. repeat process until 2 (super) vertices left in graph , single edge smallest weight between them added. mbst found consisting of edges found in previous steps. pseudocode the procedure has 2 input parameters. g graph, w weights array of edges in graph g. 1 function mbst(graph g, w
