Graph theory can be applied to solve numerous real-world optimization problems. The recommendedreadings for this module present applications of the Chinese Postman Problem (CPP) and the TravelingSalesman Problem (TSP) to reduce carbon dioxide emissions. Lukman, Cerinšek, Virtič, and Horvat (2018)developed an algorithm, based on a solution to the CPP, to optimize the route of heavy-duty vehiclesplowing and salting roads during the winter months, while Doppstadt, Koberstein, and Vigo (2016)introduced a new optimization problem, extending the TSP, to describe the delivery of goods using ahybrid electric vehicle.Your task for this discussion is as follows:1. Research other applications of graph theory to solve real-world problems and share yourfavorite one with the class.2. Discuss the importance of this application.
