Towards Run-time Checks Simplification via Term Hiding

Authors: Nataliia Stulova, Jose F. Morales, and Manuel V. Hermenegildo

Published in: OASIcs, Volume 58, Technical Communications of the 33rd International Conference on Logic Programming (ICLP 2017)

Abstract
One of the most attractive features of untyped languages for programmers is the flexibility in term creation and manipulation. However, with such power comes the responsibility of ensuring correctness of operations. A solution is adding run-time checks to the program via assertions, but this can introduce overheads that are in many cases impractical. While such overheads can be greatly reduced with static analysis, the gains depend strongly on the quality of the information inferred. Reusable libraries, i.e., library modules that are pre-compiled independently of the client, pose special challenges in this context. We propose a relaxed form of atom-based module system (which hides only a selected set of functor symbols but still provides a strict mechanism to prevent breaking visibility rules across modules) that can enrich significantly the shape information that can be inferred in reusable modular programs. We also propose an improved run-time checking approach that takes advantage of the proposed mechanisms to achieve large reductions in overhead, closer to those of static languages even in the reusable-library context. While the approach is general and system-independent, we present it for concreteness in the context of the Ciao assertion language and combined static/dynamic checking framework. Our method maintains full expressiveness of the checks in this context. Contrary to other approaches it does not introduce the need to switch the language to (static) type systems, which is known to change the semantics in languages like Prolog. We also study the approach experimentally and evaluate the overhead reduction achieved in the run-time checks.

Datalog for Enterprise Software: from Industrial Applications to Research (Invited Talk)

Authors: Molham Aref

Published in: LIPIcs, Volume 7, Technical Communications of the 26th International Conference on Logic Programming (2010)

Abstract
LogicBlox is a platform for the rapid development of enterprise applications in the domains of decision automation, analytics, and planning. Although the LogicBlox platform embodies several components and technology decisions (e.g., an emphasis on software-as- a-service), the key substrate and glue is an implementation of the Datalog language. All application development on the LogicBlox platform is done declaratively in Datalog: The language is used to query large data sets, but also to develop web and desktop GUIs (with the help of pre-defined libraries), to interface with solvers, statistics tools, and optimizers for complex analytics solutions, and to express the overall business logic of the application. The goal of this talk is to present both the business case for Datalog and the fruitful interaction of research and industrial applications in the LogicBlox context.

A Logical Paradigm for Systems Biology (Invited Talk)

Authors: François Fages

Published in: LIPIcs, Volume 7, Technical Communications of the 26th International Conference on Logic Programming (2010)

Abstract
Biologists use diagrams to represent complex systems of interaction between molecular species. These graphical notations encompass two types of information: interactions (e.g. protein complexation, modification, binding to a gene, etc.) and regulations (of an interaction or a transcription). Based on these structures, mathematical models can be developed by equipping such molecular interaction networks with kinetic expressions leading to quantitative models of mainly two kinds: ordinary differential equations for a continuous interpretation of the kinetics and continuous-time Markov chains for a stochastic interpretation of the kinetics. Since 2002, we investigate the transposition of programming concepts and tools to the analysis of living processes at the cellular level.

Runtime Addition of Integrity Constraints in an Abductive Proof Procedure

Authors: Marco Alberti, Marco Gavanelli, and Evelina Lamma

Published in: LIPIcs, Volume 7, Technical Communications of the 26th International Conference on Logic Programming (2010)

Abstract
Abductive Logic Programming is a computationally founded representation of abductive reasoning. In most ALP frameworks, integrity constraints express domainspecific logical relationships that abductive answers are required to satisfy. Integrity constraints are usually known a priori. However, in some applications (such as interactive abductive logic programming, multi-agent interactions, contracting) it makes sense to relax this assumption, in order to let the abductive reasoning start with incomplete knowledge of integrity constraints, and to continue without restarting when new integrity constraints become known. In this paper, we propose a declarative semantics for abductive logic programming with addition of integrity constraints during the abductive reasoning process, an operational instantiation (with formal termination, soundness and completeness properties) and an implementation of such a framework based on the SCIFF language and proof procedure.

Learning Domain-Specific Heuristics for Answer Set Solvers

Authors: Marcello Balduccini

Published in: LIPIcs, Volume 7, Technical Communications of the 26th International Conference on Logic Programming (2010)

Abstract
In spite of the recent improvements in the performance of Answer Set Programming (ASP) solvers, when the search space is sufficiently large, it is still possible for the search algorithm to mistakenly focus on areas of the search space that contain no solutions or very few. When that happens, performance degrades substantially, even to the point that the solver may need to be terminated before returning an answer. This prospect is a concern when one is considering using such a solver in an industrial setting, where users typically expect consistent performance. To overcome this problem, in this paper we propose a technique that allows learning domain-specific heuristics for ASP solvers. The learning is done off-line, on representative instances from the target domain, and the learned heuristics are then used for choice-point selection. In our experiments, the introduction of domain-specific heuristics improved performance on hard instances by up to 3 orders of magnitude (and 2 on average), nearly completely eliminating the cases in which the solver had to be terminated because the wait for an answer had become unacceptable.

HEX Programs with Action Atoms

Authors: Selen Basol, Ozan Erdem, Michael Fink, and Giovambattista Ianni

Published in: LIPIcs, Volume 7, Technical Communications of the 26th International Conference on Logic Programming (2010)

Abstract
HEX programs were originally introduced as a general framework for extending declarative logic programming, under the stable model semantics, with the possibility of bidirectionally accessing external sources of knowledge and/or computation. The original framework, however, does not deal satisfactorily with stateful external environments: the possibility of predictably influencing external environments has thus not yet been considered explicitly. This paper lifts HEX programs to ACTHEX programs: ACTHEX programs introduce the notion of action atoms, which are associated to corresponding functions capable of actually changing the state of external environments. The execution of specific sequences of action atoms can be declaratively programmed. Furthermore, ACTHEX programs allow for selecting preferred actions, building on weights and corresponding cost functions. We introduce syntax and semantics of acthex programs; ACTHEX programs can successfully be exploited as a general purpose language for the declarative implementation of executable specifications, which we illustrate by encodings of knowledge bases updates, action languages, and an agent programming language. A system capable of executing ACTHEX programs has been implemented and is publicly available.

Communicating Answer Set Programs

Authors: Kim Bauters, Jeroen Janssen, Steven Schockaert, Dirk Vermeir, and Martine De Cock

Published in: LIPIcs, Volume 7, Technical Communications of the 26th International Conference on Logic Programming (2010)

Abstract
Answer set programming is a form of declarative programming that has proven very successful in succinctly formulating and solving complex problems. Although mechanisms for representing and reasoning with the combined answer set programs of multiple agents have already been proposed, the actual gain in expressivity when adding communication has not been thoroughly studied. We show that allowing simple programs to talk to each other results in the same expressivity as adding negation-as-failure. Furthermore, we show that the ability to focus on one program in a network of simple programs results in the same expressivity as adding disjunction in the head of the rules.

Implementation Alternatives for Bottom-Up Evaluation

Authors: Stefan Brass

Published in: LIPIcs, Volume 7, Technical Communications of the 26th International Conference on Logic Programming (2010)

Abstract
Bottom-up evaluation is a central part of query evaluation / program execution in deductive databases. It is used after a source code optimization like magic sets or SLDmagic that ensures that only facts relevant for the query can be derived. Then bottom-up evaluation simply performs the iteration of the standard TP -operator to compute the minimal model. However, there are different ways to implement bottom-up evaluation efficiently. Since this is most critical for the performance of a deductive database system, and since performance is critical for the acceptance of deductive database technology, this question deserves a thorough analysis. In this paper we start this work by discussing several different implementation alternatives. Especially, we propose a new implementation of bottom-up evaluation called "Push-Method".

Inductive Logic Programming as Abductive Search

Authors: Domenico Corapi, Alessandra Russo, and Emil Lupu

Published in: LIPIcs, Volume 7, Technical Communications of the 26th International Conference on Logic Programming (2010)

Abstract
We present a novel approach to non-monotonic ILP and its implementation called TAL (Top-directed Abductive Learning). TAL overcomes some of the completeness problems of ILP systems based on Inverse Entailment and is the first top-down ILP system that allows background theories and hypotheses to be normal logic programs. The approach relies on mapping an ILP problem into an equivalent ALP one. This enables the use of established ALP proof procedures and the specification of richer language bias with integrity constraints. The mapping provides a principled search space for an ILP problem, over which an abductive search is used to compute inductive solutions.
