A Time-Triggered Dimension Reduction Algorithm for the Task Assignment Problem
Han Wang, Kostas Margellos, Antonis Papachristodoulou
The task assignment problem is fundamental in combinatorial optimisation, aiming at allocating one or more tasks to a number of agents while minimizing the total cost or maximizing…
Safety Verification and Controller Synthesis for Systems with Input Constraints
Han Wang, Kostas Margellos, Antonis Papachristodoulou
In this paper we consider the safety verification and safe controller synthesis problems for nonlinear control systems. The Control Barrier Certificates (CBC) approach is proposed…
Explicit Solutions for Safety Problems Using Control Barrier Functions
Han Wang, Kostas Margellos, Antonis Papachristodoulou
The control Barrier function approach has been widely used for safe controller synthesis. By solving an online convex quadratic programming problem, an optimal safe controller can…
On the sensitivity of linear resource sharing problems to the arrival of new agents
Alessandro Falsone, Kostas Margellos, Jacopo Zizzo +2
We consider a multi-agent optimal resource sharing problem that is represented by a linear program. The amount of resource to be shared is fixed, and agents belong to a population…
On the probabilistic feasibility of solutions in multi-agent optimization problems under uncertainty
George Pantazis, Filiberto Fele, Kostas Margellos
We investigate the probabilistic feasibility of randomized solutions to two distinct classes of uncertain multi-agent optimization programs. We first assume that only the constrain…
Approximate Dynamic Programming for Delivery Time Slot Pricing: a Sensitivity Analysis
Denis Lebedev, Kostas Margellos, Paul Goulart
We consider the revenue management problem of finding profit-maximising prices for delivery time slots in the context of attended home delivery. This multi-stage optimal control pr…
