| Abstract: | A maximum entropy model is used to calculate the OD distribution matrix and then a differential evolution algorithm is applied to the maximum entropy model. By introducing the differential evolution algorithm the algorithm can improve the speed and accuracy of solving maximum entropy model, thus improving the accuracy of calculating OD matrix. Finally, a simply example is taken to analyse the efficiency of this method. |
