Dynamic Multiple Vehicle Routing under Energy Capacity Constraints
Polychronis G., Lalis S. (2020)The multiple vehicle routing problem (mVRP) concerns the scheduling of multiple vehicles so as to visit some locations of interest. We study a dynamic version of mVRP where the travel costs are not a priori known and may ... -
Dynamic Vehicle Routing Under Uncertain Energy Consumption and Energy Gain Opportunities
Polychronis G., Lalis S. (2021)The amount of energy that needs to be spent by a vehicle to travel between different locations, and the amount of energy that can be regained at certain locations, may not always be known in advance with certainty. In this ... -
Dynamic vehicle routing under uncertain travel costs and refueling opportunities
Polychronis G., Lalis S. (2019)We study the vehicle routing problem for a system where there is some uncertainty regarding both the cost of travel and the refueling opportunities. Travel cost stands for the energy spent by the vehicle to move between ... -
Planning Computation Offloading on Shared Edge Infrastructure for Multiple Drones
Polychronis G., Lalis S. (2022)Drones are used in a wide range of applications, which may involve computationally-demanding data processing tasks during the missions. While such heavy tasks can be offloaded to nearby edge-servers, this may not always ... -
Safe Optimistic Path Planning for Autonomous Drones under Dynamic Energy Costs
Polychronis G., Lalis S. (2021)Unmanned aerial vehicles or so-called drones are already used in several applications to perform different sensing and monitoring missions. A central problem is to plan these missions so as to minimize the completion time. ... -
Tournament selection algorithm for the multiple travelling salesman problem
Polychronis G., Lalis S. (2020)The multiple Travelling Salesman Problem (mTSP) is a generalization of the classic TSP problem, where the cities in question are visited using a team of salesmen, each one following a different, complementary route. Several ...
