Asymptotically Optimal Bounds for OBDDs and the Solution of Some Basic OBDD Problemsany areas of application are verification, model checking, and computer aided design. For many functions it is easy to estimate the OBDD size but asymptotically optimal bounds are only known in simple situations.

Reasoning about Idealized ALGOL Using Regular Languagessoning inherits its desirable theoretical properties. The method is mathematically elementary and formal, which makes it uniquely suitable for automation. We show that reasoning can be carried out using only a meta-language of extended regular expressions, a language for which equivalence is formally decidable.作者: 邪惡的你 時(shí)間: 2025-3-28 23:45 作者: LAP 時(shí)間: 2025-3-29 05:42
