Generalization is a key feature to support state-space abstraction in IC3-based algorithms for software model checking, such as Tree-IC3 or IC3CFA. This paper introduces several improvements that range from efficient caching of generalizations over variable reductions to syntax-oriented generalization. Our techniques are generic in that they are independent of the underlying theory, and some of them are even applicable to IC3 in general. Their evaluation on multiple benchmarks, including a significant subset of the SV-COMP 2017 benchmarks, yields promising results.
