HW MUST BE TURNED IN your assignment in the hw box for CMPSC 130B (ENGR I 2108). 1 Problem { 18 points } { Minimum Cost Spanning Trees } Draw a minimum cost spanning tree constructed by Kruskals algorithm for the following graph G . Give intermediate steps. Draw a minimum cost spanning tree constructed by Prims algorithm (always growing the tree that has vertex 1 ( s = 1)) for the following graph G . You will be growing the tree that has vertex 1. Give intermediate steps. Draw a minimum cost spanning tree constructed by Sollins algorithm. Give intermediate steps.

Now we are interested in loading the least number of containers, provided that none of the remaining containers (the ones left out) can be loaded onto the ship without exceeding the cargo capacity. An obvious greedy algorithm for this...
