Spider Diagrams of Order and a Hierarchy of Star-Free Regular Languages
Abstract. The spider diagram logic forms a fragment of constraint diagram logic and is designed to be primarily used as a diagrammatic software specification tool. Our interest is ...

Deciding low levels of tree-automata hierarchy
The paper discusses the hierarchy of indices of finite automata over infinite objects. This hierarchy corresponds exactly to the hierarchy of alternations of least and greatest fi...

Approximability of Clausal Constraints
We study a family of problems, called Maximum Solution (Max Sol), where the objective is to maximise a linear goal function over the feasible integer assignments to a set of variab...

On Reasoning about Structural Equality in XML: A Description Logic Approach
We define a boolean complete description logic dialect called DLFDreg that can be used to reason about structural equality in semistructured ordered data in the presence of docume...

An automata-theoretic approach to constraint LTL
We consider an extension of linear-time temporal logic (LTL) with constraints interpreted over a concrete domain. We use a new automata-theoretic technique to show pspace decidabi...
