Quantifier reasoning in Satisfiability Modulo Theories (SMT) is a long-standing challenge. The practical method employed in modern SMT solvers is to instantiate quantified formulas...
Logical properties of iterations of relational structures are studied and these decidability results are applied to the model checking of a powerful extension of pushdown systems....
We define the class of micro-macro stack graphs, a new class of graphs modeling infinite-state sequential systems with a decidable model-checking problem. Micro-macro stack grap...
Mitigating the devastating ramifications of major disasters requires emergency workers to respond in a maximally efficient way. Information systems can improve their efficiency by ...
Recent years have witnessed the wide recognition of the importance of ontology and rule in the AI research. In this paper, we report our implementation and evaluation of a rule-ba...
