Compression of enumerations and gain

no code implementations6 Apr 2023 George Barmpalias, Xiaoyan Zhang, Bohua Zhan

We study the compressibility of enumerations, and its role in the relative Kolmogorov complexity of computably enumerable sets, with respect to density.

NIL: Learning Nonlinear Interpolants

no code implementations28 May 2019 Mingshuai Chen, Jian Wang, Jie An, Bohua Zhan, Deepak Kapur, Naijun Zhan

Nonlinear interpolants have been shown useful for the verification of programs and hybrid systems in contexts of theorem proving, model checking, abstract interpretation, etc.

Automated Theorem Proving
