| Research Abstract |
The vehicle routing problem is the problem of minimizing the total cost of a number of vehicles, under various constraints, where every customer must be visited exactly once by a vehicle. Although this problem has a wide range of applications, it is difficult to obtain an optimal solution. The objective of this research is to find a high quality solution in a reasonable time. We proposed a method of reducing an instance and an algorithm that searches the large solution space efficiently by incorporating it.
