The graph聮s depth-first search and Branch-and -bound algorithm were presented. The algorithm was used in an example. As the result, the time cost of the optimized fleet assignment for 70 flights a day with 12 A320 aircrafts was less than 0.3 second, which was one order of magnitude ...

A significant number of optimization problems like production planning, crew scheduling can’t be solved in polynomial time, and they belong to the NP-Hard class. These problems are the example of NP-Hard combinatorial optimization problem. Branch and bound (B&B) is an algorithm paradigm widely ...

bound is derived by use of aminimum spanning treethat consists of the unvisited vertices, as well as the root and leaf vertices of the partial route. For example, for the unfinished route A→B→E, a minimum spanning tree is built for nodes A, C, D, and E, and its value is 12. ...
