MASP-Reduce: A Proposal for Distributed Computation of Stable Models

Authors: Federico Igne, Agostino Dovier, and Enrico Pontelli

Published in: OASIcs, Volume 64, Technical Communications of the 34th International Conference on Logic Programming (ICLP 2018)

Abstract
There has been an increasing interest in recent years towards the development of efficient solvers for Answer Set Programming (ASP) and towards the application of ASP to solve increasing more challenging problems. In particular, several recent efforts have explored the issue of scalability of ASP solvers when addressing the challenges caused by the need to ground the program before resolution. This paper offers an alternative solution to this challenge, focused on the use of distributed programming techniques to reason about ASP programs whose grounding would be prohibitive for mainstream ASP solvers. The work builds on a proposal of a characterization of answer set solving as a form of non-standard graph coloring. The paper expands this characterization to include syntactic extensions used in modern ASP (e.g., choice rules, weight constraints). We present an implementation of the solver using a distributed programming framework specifically designed to manipulate very large graphs, as provided by Apache Spark, which in turn builds on the MapReduce programming framework. Finally, we provide a few preliminary results obtained from the first prototype implementation of this approach.

BAAC: A Prolog System for Action Description and Agents Coordination

Authors: Agostino Dovier, Andrea Formisano, and Enrico Pontelli

Published in: LIPIcs, Volume 11, Technical Communications of the 27th International Conference on Logic Programming (ICLP'11) (2011)

Abstract
The paper presents a system for knowledge representation and coordination, where autonomous agents reason and act in a shared environment. Agents autonomously pursue individual goals, but can interact through a shared knowledge repository. In their interactions, agents deal with problems of synchronization and concurrency, and have to realize coordination by developing proper strategies in order to ensure a consistent global execution of their autonomously derived plans. This kind of knowledge is modeled using an extension of the action description language B. A distributed planning problem is formalized by providing a number of declarative specifications of the portion of the problem pertaining a single agent. Each of these specifications is executable by a stand-alone CLP-based planner. The coordination platform, implemented in Prolog, is easily modifiable and extensible. New user-defined interaction protocols can be integrated.
