Here everything is provided to reproduce the experimentation results of "HiFrog with lattice refinement" published in VSTTE 2018 and Memocode 2019:
HiFrog with Lattice Refinement:
Lattice-Based Counterexample-Guided Refinement Algorithm offers refinement for Bounded Model Checking with SMT solvers of programs using a library of either standard or user-defined functions.
Typically, if the program correctness depends on the output of a library function, the model-checking process either treats this function as an uninterpreted function, or is required to use a theory under which the function in question is fully defined. The former approach leads to numerous spurious counter-examples, whereas the latter faces the danger of the state-explosion problem, where the resulting formula is too large to be solved by means of modern SMT solvers.
We suggest using a lattice with properties of mathematical functions to model library functions in programs with EUF or extensions of EUF. We present  the full details of our lattice-based refinement algorithm and propose an algorithm for constructing a lattice of literals from a set of properties, each of which is encoded into one or more summaries. We present  (full version here) the LB-CEGAR algorithm, a full and generalised algorithm of the lattice-based refinement algorithm for programs with multiple different library functions call. The algorithm represents a function efficiently via a lattice of literals (as first-order formulas) and gradually refines the current representation of this function according to the partial order of literals even if we do not have or wish to use the full definition of this function.
