Abstract:
AbstractThe numerically definite syllogistic is the fragment of English obtained by extending the language of the classical syllogism with numerical quantifiers. The numerically definite relational syllogistic is the fragment of English obtained by extending the numerically definite syllogistic with predicates involving transitive verbs. This paper investigates the computational complexity of the satisfiability problem for these fragments. We show that the satisfiability problem (= finite satisfiability problem) for the numerically definite syllogistic is strongly NP-complete, and that the satisfiability problem (= finite satisfiability problem) for the numerically definite relational syllogistic is NEXPTIME-complete, but perhaps not strongly so. We discuss the related problem of probabilistic (propositional) satisfiability, and thereby demonstrate the incompleteness of some proof-systems that have been proposed for the numerically definite syllogistic.

Abstract:
We present a SAT-based framework for LTLf (Linear Temporal Logic on Finite Traces) satisfiability checking. We use propositional SAT-solving techniques to construct a transition system for the input LTLf formula; satisfiability checking is then reduced to a path-search problem over this transition system. Furthermore, we introduce CDLSC (Conflict-Driven LTLf Satisfiability Checking), a novel algorithm that leverages information produced by propositional SAT solvers from both satisfiability and unsatisfiability results. Experimental evaluations show that CDLSC outperforms all other existing approaches for LTLf satisfiability checking, by demonstrating an approximate four-fold speed-up compared to the second-best solver.

Abstract:
In this dissertation we investigate theoretical aspects of some practical approaches used in solving and understanding search problems. We concentrate on the Satisfiability problem, which is a strong representative from search problem domains. The work develops general theoretical foundations to investigate some practical aspects of satisfiability search. This results in a better understanding of the fundamental mechanics for search algorithm construction and behaviour. A theory of choice or branching heuristics is presented, accompanied by results showing a correspondence of both parameterisations and performance when the method is compared to previous empirically motivated branching techniques. The logical foundations of the backtracking mechanism are explored alongside formulations for reasoning in relevant logics which results in the development of a malleable backtracking mechanism that subsumes other intelligent backtracking proof construction techniques and allows the incorporation of proof rearrangement strategies. Moreover, empirical tests show that relevant backtracking outperforms all other forms of intelligent backtracking search tree construction methods. An investigation into modelling and generating world problem instances justifies a modularised problem model proposal which is used experimentally to highlight the practicability of search algorithms for the proposed model and related domains.

Full text
Abstract:
Since 1992 a popular and appealing technique for solving planning problems has been to use a general purpose solution procedure for Boolean SAT(isfiability) problems. In this setting, a fixed horizon instance of the problem is encoded as a formula in propositional logic. A SAT procedure then computes a satisfying valuation for that formula, or otherwise proves it unsatisfiable. Here, the SAT encoding is constructive in the usual sense that there is a one-to-one correspondence between plans –i.e., solutions to the planning problem– and satisfying valuations of the formula. One of the biggest drawbacks of this approach is the enormous sized formulae generated by the proposed encodings. In this thesis we mitigate that problem by developing, implementing, and evaluating a novel encoding that uses the techniques of splitting and factoring to develop a compact encoding that is amenable to state-of-the-art SAT procedures. Overall, our approach is the most scalable, and our representation the most compact amongst optimal planning procedures. We then examine planning with numeric quantities, and in particular optimal planning with action costs. SAT-based procedures have previously been proposed in this setting for the fixed horizon case, where there is a given limit on plan length, however a key challenge has been to develop a SAT-based procedure that can achieve horizon-independent optimal solutions – i.e., the least costly plan irrespective of length. Meeting that challenge, in this thesis we develop a novel horizon-independent optimal procedure that poses partially weighted MaxSAT problems to our own cost-optimising conflict-driven clause learning (CDCL) procedure. We perform a detailed empirical evaluation of our approach, detailing the types of problem structures where it dominates. Finally, we take the insights gleaned for the classical propositional planning case, and develop a number of encodings of problems that are described using control-knowledge. That control knowledge expresses domain-dependent constraints which: (1) constrain the space of admissible plans, and (2) allow the compact specification of constraints on plans that cannot be naturally or efficiently specified in classical propositional planning. Specifically, in this thesis we develop encodings for planning using temporal logic based constraints, procedural knowledge written in a language based on ConGolog, and Hierarchical Task Network based constraints. Our compilations use the technique of splitting to achieve relatively compact encodings compared to existing compilations. In contrast to similar work in the field of answer set planning, our compilations admit plans in the parallel format, a feature that is crucial for the performance of SAT-based planning.

Oe, Duck Ki. "Formally certified satisfiability solving." Diss., University of Iowa, 2012. https://ir.uiowa.edu/etd/3362.

Full text
Abstract:
Satisfiability (SAT) and satisfiability modulo theories (SMT) solvers are high-performance automated propositional and first-order theorem provers, used as underlying tools in many formal verification and artificial intelligence systems. Theoretic and engineering advancement of solver technologies improved the performance of modern solvers; however, the increased complexity of those solvers calls for formal verification of those tools themselves. This thesis discusses two methods to formally certify SAT/SMT solvers. The first method is generating proofs from solvers and certifying those proofs. Because new theories are constantly added to SMT solvers, a flexible framework to safely add new inference rules is necessary. The proposal is to use a meta-language called LFSC, which is based on Edinburgh Logical Framework. SAT/SMT logics have been encoded in LFSC, and the encoding can be easily and modularly extended for new logics. It is shown that an optimized LFSC checker can certify SMT proofs efficiently. The second method is using a verified programming language to implement a SAT solver and verify the code statically. Guru is a pure functional programming language with support for dependent types and theorem proving; Guru also allows for efficient code generation by means of resource typing. A modern SAT solver, called versat, has been implemented and verified to be correct in Guru. The performance of versat is shown to be comparable with that of the current proof checking technology.

Abstract:
This dissertation explores approaches to the satisfiability problem, focusing on local search methods. The research endeavours to better understand how and why some local search methods are effective. At the root of this understanding are a set of metrics that characterize the behaviour of local search methods. Based on this understanding, two new local search methods are proposed and tested, the first, SDF, demonstrating the value of the insights drawn from the metrics, and the second, ESG, achieving state-of-the-art performance and generalizing the approach to arbitrary 0-1 integer linear programming problems. This generality is demonstrated by applying ESG to combinatorial auction winner determination. Further augmentations to local search are proposed and examined, exploring hybrids that incorporate aspects of backtrack search methods.

Abstract:

This thesis presents exact means to solve a family of NP-hard problems. Starting with the well-studied Exact Satisfiability problem (XSAT) parents, siblings and daughters are derived and studied, each with interesting practical and theoretical properties. While developing exact algorithms to solve the problems, we gain new insights into their structure and mutual similarities and differences.

Given a Boolean formula in CNF, the XSAT problem asks for an assignment to the variables such that each clause contains exactly one true literal. For this problem we present an O(1.1730n) time algorithm, where n is the number of variables. XSAT is a special case of the General Exact Satisfiability problem which asks for an assignment such that in each clause exactly i literals be true. For this problem we present an algorithm which runs in O(2(1-ε) n) time, with 0 < ε < 1 for every fixed i; for i=2, 3 and 4 we have running times in O(1.4511n), O(1.6214n) and O(1.6848n) respectively.

For the counting problems we present an O(1.2190n) time algorithm which counts the number of models for an XSAT instance. We also present algorithms for #2SATw and #3SATw, two well studied Boolean problems. The algorithms have running times in O(1.2561n) and O(1.6737n) respectively.

Finally we study optimisation problems: As a variant of the Maximum Exact Satisfiability problem, consider the problem of finding an assignment exactly satisfying a maximum number of clauses while the rest are left with no true literal. This problem is reducible to #2SATw without the addition of new variables and thus is solvable in time O(1.2561n). Another interesting optimisation problem is to find two XSAT models which differ in as many variables as possible. This problem is shown to be solvable in O(1.8348n) time.

Abstract:
In Description Logics (DLs), both tableau-based and automatabased algorithms are frequently used to show decidability and complexity results for basic inference problems such as satisfiability of concepts. Whereas tableau-based algorithms usually yield worst-case optimal algorithms in the case of PSpace-complete logics, it is often very hard to design optimal tableau-based algorithms for ExpTime-complete DLs. In contrast, the automata-based approach is usually well-suited to prove ExpTime upper-bounds, but its direct application will usually also yield an ExpTime-algorithm for a PSpace-complete logic since the (tree) automaton constructed for a given concept is usually exponentially large. In the present paper, we formulate conditions under which an on-the-fly construction of such an exponentially large automaton can be used to obtain a PSpace-algorithm. We illustrate the usefulness of this approach by proving a new PSpace upper-bound for satisfiability of concepts w.r.t. acyclic terminologies in the DL SI, which extends the basic DL ALC with transitive and inverse roles.

Abstract:
The tableau algorithm implemented in the FaCT knowledge representation system decides satisfiability and subsumption in SHIQ, a very expressive description logic providing, e.g., inverse and transitive roles, number restrictions, and general axioms. Intuitively, the algorithm searches for a tree-shaped abstraction of a model. To ensure termination of this algorithm without comprimising correctness, it stops expanding paths in the search tree using a so-called 'double-blocking' condition.

Abstract:
We analyze the complexity of finite model reasoning in the description logic ALCQI, i.e. ALC augmented with qualifying number restrictions, inverse roles, and general TBoxes. It turns out that all relevant reasoning tasks such as concept satisfiability and ABox consistency are EXPTIME-complete, regardless of whether the numbers in number restrictions are coded unarily or binarily. Thus, finite model reasoning with ALCQI is not harder than standard reasoning with ALCQI.
