Description: This procedure is to use branch and bound procedure for seeking the shortest path, using C++ to implement. The basic idea is: Using the minimum priority queue Branch and Bound method to build a program, the details are: for each node, containing three varibles: the current path length traversed, the current cost and the node number corresponding to the actual city. On the determination of priorities, we first use the current path length traversed to determine the priority if the path length is equal, then current cost is used to determine priority. At the same time, we also define two arrays dist [i] and the pric [i] to save the current shortest distance and cost from the source city to every other city . This will be used as the evaluation criterion when pruning.
