Efficient Local Search for Nonlinear Real Arithmetic
Zhonghan Wang, Bohua Zhan, Bohan Li +1
Local search has recently been applied to SMT problems over various arithmetic theories. Among these, nonlinear real arithmetic poses special challenges due to its uncountable solu…
Learning One-Clock Timed Automata
Jie An, Mingshuai Chen, Bohua Zhan +2
We present an algorithm for active learning of deterministic timed automata with a single clock. The algorithm is within the framework of Angluin's algorithm and inspired by…
NIL: Learning Nonlinear Interpolants
Mingshuai Chen, Jian Wang, Jie An +3
Nonlinear interpolants have been shown useful for the verification of programs and hybrid systems in contexts of theorem proving, model checking, abstract interpretation, etc. The…
HolPy: Interactive Theorem Proving in Python
Bohua Zhan
HolPy is an interactive theorem proving system implemented in Python. It uses higher-order logic as the logical foundation. Its main features include a pervasive use of macros in p…
Verifying Asymptotic Time Complexity of Imperative Programs in Isabelle
Bohua Zhan, Maximilian P. L. Haslbeck
We present a framework in Isabelle for verifying asymptotic time complexity of imperative programs. We build upon an extension of Imperative HOL and its separation logic to include…
Formalization of the fundamental group in untyped set theory using auto2
Bohua Zhan
We present a new framework for formalizing mathematics in untyped set theory using auto2. Using this framework, we formalize in Isabelle/FOL the entire chain of development from th…
