    Cooperation in self-organized heterogeneous swarms

    Get PDF
    Cooperation in self-organized heterogeneous swarms is a phenomenon from nature with many applications in autonomous robots. I specifically analyzed the problem of auto-regulated team formation in multi-agent systems and several strategies to learn socially how to make multi-objective decisions. To this end I proposed new multi-objective ranking relations and analyzed their properties theoretically and within multi-objective metaheuristics. The results showed that simple decision mechanism suffice to build effective teams of heterogeneous agents and that diversity in groups is not a problem but can increase the efficiency of multi-agent systems

    This volume, LNAI 13385, constitutes the refereed proceedings of the 11th International Joint Conference on Automated Reasoning, IJCAR 2022, held in Haifa, Israel, in August 2022. The 32 full research papers and 9 short papers presented together with two invited talks were carefully reviewed and selected from 85 submissions. The papers focus on the following topics: Satisfiability, SMT Solving,Arithmetic; Calculi and Orderings; Knowledge Representation and Jutsification; Choices, Invariance, Substitutions and Formalization; Modal Logics; Proofs System and Proofs Search; Evolution, Termination and Decision Prolems. This is an open access book

    Fuelling the zero-emissions road freight of the future: routing of mobile fuellers

    Get PDF
    The future of zero-emissions road freight is closely tied to the sufficient availability of new and clean fuel options such as electricity and Hydrogen. In goods distribution using Electric Commercial Vehicles (ECVs) and Hydrogen Fuel Cell Vehicles (HFCVs) a major challenge in the transition period would pertain to their limited autonomy and scarce and unevenly distributed refuelling stations. One viable solution to facilitate and speed up the adoption of ECVs/HFCVs by logistics, however, is to get the fuel to the point where it is needed (instead of diverting the route of delivery vehicles to refuelling stations) using "Mobile Fuellers (MFs)". These are mobile battery swapping/recharging vans or mobile Hydrogen fuellers that can travel to a running ECV/HFCV to provide the fuel they require to complete their delivery routes at a rendezvous time and space. In this presentation, new vehicle routing models will be presented for a third party company that provides MF services. In the proposed problem variant, the MF provider company receives routing plans of multiple customer companies and has to design routes for a fleet of capacitated MFs that have to synchronise their routes with the running vehicles to deliver the required amount of fuel on-the-fly. This presentation will discuss and compare several mathematical models based on different business models and collaborative logistics scenarios

    Proceedings of the GPEA Polytechnic Summit 2022: Session Papers

    Get PDF
    Welcome to GPEA PS 2022 Each year the Polytechnic Summit assembles leaders, influencers and contributors who shape the future of polytechnic education. The Polytechnic Summit provides a forum to enable opportunities for collaboration and partnerships and for participants to focus on innovation in curriculum and pedagogy, to share best practices in active and applied learning, and discuss practice-based research to enhance student learning. This year a view on the aspects of applied research will be added. How to conduct research in a teaching first environment and make use of this. Which characteristics of applied research are important to be used in teaching and vice versa?The Summit will – once again - also provide an opportunity to examine the challenges and opportunities presented by COVID-19 and will offer us all an opportunity to explore the ways in which we can collaborate more effectively using our new-found virtual engagement skills and prepare for a hybrid future. PS2022 Themes: Design (Programmes, Curriculum, Organisation);Practice-Based Learning;Applied Research; Employability and Graduate Skills; Internationalisation, Global Teaching & Collaboration and Sustainability Theme

    Paradoxes of interactivity: perspectives for media theory, human-computer interaction, and artistic investigations

    Get PDF
    Current findings from anthropology, genetics, prehistory, cognitive and neuroscience indicate that human nature is grounded in a co-evolution of tool use, symbolic communication, social interaction and cultural transmission. Digital information technology has recently entered as a new tool in this co-evolution, and will probably have the strongest impact on shaping the human mind in the near future. A common effort from the humanities, the sciences, art and technology is necessary to understand this ongoing co- evolutionary process. Interactivity is a key for understanding the new relationships formed by humans with social robots as well as interactive environments and wearables underlying this process. Of special importance for understanding interactivity are human-computer and human-robot interaction, as well as media theory and New Media Art. "Paradoxes of Interactivity" brings together reflections on "interactivity" from different theoretical perspectives, the interplay of science and art, and recent technological developments for artistic applications, especially in the realm of sound
