Strong Termination for Gap-Order Constraint Abstractions of Counter Systemsich constraints (over ℤ) between the variables of the source state and the target state of a transition are . (.) . . extend monotonicity constraint systems , integral relation automata , and constraint automata in . Since . are infinitely-branching, termination does not imply ., i.e.轻信 发表于 2025-3-27 01:48:32
Approximate Regular Expressions and Their Derivatives given language. In this paper, we introduce a new family of regular operators based on a generalization of the notion of distance and we define a new family of expressions, the .. We compute Brzozowski derivatives and Antimirov derivatives of such operators, which allows us to provide two recognizeEmg827 发表于 2025-3-27 07:37:38

Conservative Groupoids Recognize Only Regular Languagesoperation ‘·’ which is not necessarily associative. It is well known that . can be recognized by a groupoid iff . is context-free. But it is also known that some subclasses of groupoids can only recognize regular languages. For example, . recognize exactly the regular open languages and Beaudry et aPsychogenic 发表于 2025-3-27 15:44:45

The Minimal Cost Reachability Problem in Priced Timed Pushdown Systemsget set of configurations, determine the minimal possible cost of any run from the initial to a target configuration. We solve the problem by reducing it to the reachability problem in standard pushdown systems.
