CHC-COMP

Constrained Horn Clauses (CHC) is a fragment of First Order Logic (FOL) that is sufficiently expressive to describe many verification, inference, and synthesis problems including inductive invariant inference, model checking of safety properties, inference of procedure summaries, regression verification, and sequential equivalence. The CHC competition (CHC-COMP) will compare state-of-the-art tools for CHC solving with respect to performance and effectiveness on a set of publicly available benchmarks. The winners among participating solvers are recognized by measuring the number of correctly solved benchmarks as well as the runtime. The results of the sixth CHC-COMP will be announced at the HCVS workshop affiliated with ETAPS 2023. CHC-COMP 2023 will also be part of TOOLympics 2023 at ETAPS 2023... The list of participants will be made public, together with the competition results, at the HCVS workshop (April 23). If you would like to submit a solver, and have not yet been in touch..
