Expressivity of Quantitative Modal Logics: Categorical Foundations via Codensity and Approximation
Yuichi Komorida, Shin-ya Katsumata, Clemens Kupke +2
A modal logic that is strong enough to fully characterize the behavior of a system is called expressive. Recently, with the growing diversity of systems to be reasoned about (proba…
Fibrational Initial Algebra-Final Coalgebra Coincidence over Initial Algebras: Turning Verification Witnesses Upside Down
Mayuko Kori, Ichiro Hasuo, Shin-ya Katsumata
The coincidence between initial algebras (IAs) and final coalgebras (FCs) is a phenomenon that underpins various important results in theoretical computer science. In this paper, w…
Decision Tree Learning in CEGIS-Based Termination Analysis
Satoshi Kura, Hiroshi Unno, Ichiro Hasuo
We present a novel decision tree-based synthesis algorithm of ranking functions for verifying program termination. Our algorithm is integrated into the workflow of CounterExample G…
