We consider an online version of the orienteering problem, where stochastic service requests arise during a first time interval from customers located on the nodes of a graph. Every request must be accepted/rejected in real time. Later, a vehicle must visit the accepted customers during a second time interval. We perform extensive computational tests on the proposed algorithms and discuss the pros and cons of the different methods. Link to the article
