We show some descriptions, written in CombSQL+ language, for the car sequencing problem. We observed that a small difference in the descriptions affects performance, and discuss the reason and an idea on improvement of the system.</p>

    This paper discusses determinization of conditional term rewriting systems with oriented constructor rules. We present a rule-based transformation system, which transforms a non-deterministic one into a deterministic one, together with examples of the transformation. We prove that the transformation system is simulation sound and simulation complete. We also prove that the transformation system is complete for some class by introducing a strategy for the transformation system.

    A reachability problem is a problem used to decide whether s is reachable to t by R or not for a given two terms s, t and a term rewriting system R. Since it is known that this problem is undecidable, effort has been devoted to finding subclasses of term rewriting systems in which the eachabilit
    y is decidable. However few works on decidability exist for innermost reduction strategy or context-sensitive rewriting.

    In this paper, we show that innermost reachability and
    context-sensitive reachability are decidable for linear right-shallow term rewriting systems. Our approach is based on the tree automata technique that is commonly
    used for analysis of reachability and its related properties.

    Length-two string rewriting systems are length-preserving string rewriting systems that consist of length-two rules. This paper shows that confluence, termination, left-most termination and right-most termination are undecidable
    properties for length-two string rewriting systems. These results mean that these properties are undecidable for
    the class of linear term rewriting systems in which depth-two variables are allowed in both-hand sides of rules.

    We enhance the dependency pair method in order to prove termination using recursive structure analysis in simply-typed term rewriting systems, which is one of the computational models of functional programs. The primary advantage of our method is that one can exclude higher-order variables which are difficult to analyze theoretically, from recursive structure analysis. The key idea of our method is to analyze recursive structure from the viewpoint of strong computability. This property was introduced for proving termination in typed lambda-calculus, and is a stronger condition than the property of termination. The difficulty in incorporating this concept into recursive structure analysis is that because it is defined inductively over type structure, it is not closed under the subterm relation. This breaks the correspondence between strong computability and recursive structure. In order to guarantee the correspondence, we propose plain function-passing as a restriction, which is satisfied by
    many non-artificial functional programs.

    "We consider several classes of term rewriting systems and prove that termination is decidable for these classes. By showing the cycling property of infinite dependency chains, we prove that termination is decidable for semi-constructor case, which is a superclass of right-ground TRSs. By analyzing argument propagation cycles in the dependency graph, we show that termination is also decidable for left-linear shallow TRSs. Moreover we extend these by combining these two techniques."
