This paper presents a hybrid harmony search algorithm based on data analysis (HSA-DA) to solve multi-objective grain transportation problem. The grain transportation problem can be summarized as the vehicle routing problem with time windows (VRPTW). It is a well-known NP-hard discrete optimization problem with two objectives: to minimize the total distance cost and to minimize the number of vehicles. In the HSA-DA, we use data analysis method to analyze the historical data of each different neighborhood search operators, and feed back the analy...
