"content": "<p>Dear pgRouting community,</p><p>I am Moaaz Tarek, a computer engineering senior student at Cairo University.</p><p>Lately i have been interested in route optimization especially the DPDPTW ( dynamic pickup and delivery problem with time window) , also i am eager to contribute to vrpRouting as a GSOC participant.</p><p>i have been researching for 2 month about the PDP and its variants and i have come across different solutions methods that i would like to implement</p><ol><li>MOEA/D: a multi-objective evolutionary algorithm with diffusion that sets multiple objectives and try to find a feasible solution using VNS as its local search method to avoid local min/max</li><li>Ant colony system with bipartite graph matching: this variant solves the DPDPTW with dynamic customer arrival. It introduce a bipartite graph matching model within the neighborhood search process and employ the KuhnMunkres (KM) matching algorithm, generally it does a Large Neighborhood search as it local search method</li></ol><p>Research papers list that these methods provide better solution in less time than the tabu search</p><p>i hope this idea would be a good fit to vrpRouting, and I would like to hear your opinions.</p><p>Thank you,Moaaz</p><br><br><a href=\"https://discourse.osgeo.org/t/gsoc-2025-introduction-idea-proposal-from-moaaz/112566/1\">Discuss this on our forum.</a>",
