Abstract

The Multi-Agent Programming Contest, MAPC, is an annual event organized since 2005 out of Clausthal University of Technology. Its aim is to investigate the potential of using decentralized, autonomously acting intelligent agents, by providing a complex scenario to be solved in a competitive environment. For this we need suitable benchmarks where agent-based systems can shine. We present previous editions of the contest and also its current scenario and results from its use in the 2019 MAPC with a special focus on its suitability. We conclude with lessons learned over the years., Comment: Submitted to the proceedings of the Multi-Agent Programming Contest 2019, to appear in Springer Lect. Notes Computer Challenges Series https://www.springer.com/series/16528

23. Improving Performance of heavily loaded agents

Abstract

With the increase in agent-based applications, there are now agent systems that support \emph{concurrent} client accesses. The ability to process large volumes of simultaneous requests is critical in many such applications. In such a setting, the traditional approach of serving these requests one at a time via queues (e.g. \textsf{FIFO} queues, priority queues) is insufficient. Alternative models are essential to improve the performance of such \emph{heavily loaded} agents. In this paper, we propose a set of \emph{cost-based algorithms} to \emph{optimize} and \emph{merge} multiple requests submitted to an agent. In order to merge a set of requests, one first needs to identify commonalities among such requests. First, we provide an \emph{application independent framework} within which an agent developer may specify relationships (called \emph{invariants}) between requests. Second, we provide two algorithms (and various accompanying heuristics) which allow an agent to automatically rewrite requests so as to avoid redundant work---these algorithms take invariants associated with the agent into account. Our algorithms are independent of any specific agent framework. For an implementation, we implemented both these algorithms on top of the \impact agent development platform, and on top of a (non-\impact) geographic database agent. Based on these implementations, we conducted experiments and show that our algorithms are considerably more efficient than methods that use the $A^*$ algorithm., Comment: 63 pages, 26 figures, 10 tables

24. Transformation-Based Bottom-Up Computation of the Well-Founded Model

Author

Subjects
Computer Science - Logic in Computer Science, I.2.3
Abstract

We present a framework for expressing bottom-up algorithms to compute the well-founded model of non-disjunctive logic programs. Our method is based on the notion of conditional facts and elementary program transformations studied by Brass and Dix for disjunctive programs. However, even if we restrict their framework to nondisjunctive programs, their residual program can grow to exponential size, whereas for function-free programs our program remainder is always polynomial in the size of the extensional database (EDB). We show that particular orderings of our transformations (we call them strategies) correspond to well-known computational methods like the alternating fixpoint approach, the well-founded magic sets method and the magic alternating fixpoint procedure. However, due to the confluence of our calculi, we come up with computations of the well-founded model that are provably better than these methods. In contrast to other approaches, our transformation method treats magic set transformed programs correctly, i.e. it always computes a relevant part of the well-founded model of the original program., Comment: 43 pages, 3 figures

25. Super Logic Programs

Abstract

The Autoepistemic Logic of Knowledge and Belief (AELB) is a powerful nonmonotic formalism introduced by Teodor Przymusinski in 1994. In this paper, we specialize it to a class of theories called `super logic programs'. We argue that these programs form a natural generalization of standard logic programs. In particular, they allow disjunctions and default negation of arbibrary positive objective formulas. Our main results are two new and powerful characterizations of the static semant ics of these programs, one syntactic, and one model-theoretic. The syntactic fixed point characterization is much simpler than the fixed point construction of the static semantics for arbitrary AELB theories. The model-theoretic characterization via Kripke models allows one to construct finite representations of the inherently infinite static expansions. Both characterizations can be used as the basis of algorithms for query answering under the static semantics. We describe a query-answering interpreter for super programs which we developed based on the model-theoretic characterization and which is available on the web., Comment: 47 pages, revised version of the paper submitted 10/2000

26. Probabilistic Agent Programs

Author

Abstract

Agents are small programs that autonomously take actions based on changes in their environment or ``state.'' Over the last few years, there have been an increasing number of efforts to build agents that can interact and/or collaborate with other agents. In one of these efforts, Eiter, Subrahmanian amd Pick (AIJ, 108(1-2), pages 179-255) have shown how agents may be built on top of legacy code. However, their framework assumes that agent states are completely determined, and there is no uncertainty in an agent's state. Thus, their framework allows an agent developer to specify how his agents will react when the agent is 100% sure about what is true/false in the world state. In this paper, we propose the concept of a \emph{probabilistic agent program} and show how, given an arbitrary program written in any imperative language, we may build a declarative ``probabilistic'' agent program on top of it which supports decision making in the presence of uncertainty. We provide two alternative semantics for probabilistic agent programs. We show that the second semantics, though more epistemically appealing, is more complex to compute. We provide sound and complete algorithms to compute the semantics of \emph{positive} agent programs., Comment: 44 pages, 1 figure, Appendix
