This repository includes the data set used in the paper "A matheuristic approach to the orienteering problem with service time dependent profits".
- kroData/file_format.md is a description of the text file that defines the network used in each Kro instance.
TIPS:
<Number of nodes> X Y Profit(p_i) MinServiceTime(r_i) ProfitCollectingCoefficient(beta_i) MustVisit 3140.0 1401.0 0.0 0.0 0.50 1 556.0 1056.0 92.0 79.0 0.38 0 ... Tmax
- The first node is the starting and ending node.
- ProfitCollectingCoefficient(beta_i) should divide by 200 when using.
- Distance between any two nodes is Euclidean distance and rounded to the closest integer.
- The data generation scheme is from "Erdogan, G. , & Laporte, G. (2013). The orienteering problem with variable profits. Networks, 61 (2), 104-116 ."
The detailed results for Kro instances listed in the mentioned paper are included in the kroData/Results_BestRoutes.csv.
-Each row shows the detailed information of the best route obtained from TSNLP(the proposed matheuristic method in our paper). -The detailed information includes the objective value, total service time, total travel time, the number of visited customers, the route sequence, and the service time for each visited customer.
