Given a set of trips in a road network, where each trip has an individual, a vehicle and some
requirements, the ridesharing problem is to select a subset of vehicles to deliver the
individuals of all trips to their destinations satisfying the requirements. Common
requirements of a trip include the source, destination, vehicle capacity, detour distance limit,
preferred paths, and time constraints of the trip. Minimizing the total travel distance of the
vehicles and minimizing the number of vehicles are major optimization goals. These …
