The six datasets are used in the following paper: Wenzheng Xu , Weifa Liang, Zichuan Xu, Jian Peng, Dezhong Peng, Tang Liu, Xiaohua Jia, and Sajal K. Das,“Approximation algorithms for the generalized team orienteering problem and its applications,”which was submitted to journal IEEE/ACM Transactions on Networking (ToN) . Specific descriptions for the datasets: 1. GTOP-chargingPerformanceTable.xlsx: the performance comparison of different algorithms in rechargable sensor networks. Some results were published in the following paper: Wenzheng Xu, Zichuan Xu, Jian Peng, Weifa Liang, Tang Liu, Xiaohua Jia, and Sajal K. Das,“Approximation algorithms for the team orienteering problem,”in Proc. 39th IEEE International Conference on Computer Communications (INFOCOM), 2020, pp. 1389–1398. 2.
