This presentation is my grad school's thesis seminar (September 2012). Still discuss about Vehicle Routing Problem (VRP), but with additional solving methods. The last presentation (discuss about VRPSPD) was only solved with Genetic Algorithm, however, in this presentation additional Local Search also used to help GA solved the problem faster and more efficient. That's why we call it "Hybrid Genetic Algorithm". The constraint itself also added, beside Simultaneous Pickup and Delivery (SPD), Time Window and Multi Trips are included.
Hopefully this simple presentation could enhance your knowledge about VRP and Genetic Algorithm.
