Compositional Value Iteration with Pareto Caching

K Watanabe, M Vegt, S Junges, I Hasuo - International Conference on …, 2024 - Springer
The de-facto standard approach in MDP verification is based on value iteration (VI). We
propose compositional VI, a framework for model checking compositional MDPs, that …

Compositional probabilistic model checking with string diagrams of MDPs

K Watanabe, C Eberhart, K Asada, I Hasuo - International Conference on …, 2023 - Springer
We present a compositional model checking algorithm for Markov decision processes, in
which they are composed in the categorical graphical language of string diagrams. The …

Pareto Curves for Compositionally Model Checking String Diagrams of MDPs

K Watanabe, M van der Vegt, I Hasuo, J Rot… - … Conference on Tools …, 2024 - Springer
Computing schedulers that optimize reachability probabilities in MDPs is a standard
verification task. To address scalability concerns, we focus on MDPs that are compositionally …

Following our recent development of a compositional model checking algorithm for Markov
decision processes, we present a compositional framework for solving mean payoff games …

Game comonads and beyond: compositional constructions for logic and algorithms

A Connolly - 2023 - repository.cam.ac.uk
Game comonads represent a rare application of category theoretic methods to the fields of
finite model theory and descriptive complexity. First introduced by Abramsky, Dawar and …

Pareto Fronts for Compositionally Solving String Diagrams of Parity Games

K Watanabe - arXiv preprint arXiv:2406.17240, 2024 - arxiv.org
Open parity games are proposed as a compositional extension of parity games with
algebraic operations, forming string diagrams of parity games. A potential application of …

A compositional framework for Petri nets

S Lechenne, C Eberhart, I Hasuo - International Workshop on Coalgebraic …, 2024 - Springer
We define a bidirectional compositional framework for Petri nets based on a line of work
about compositionally defining games and computation models. This relies on defining …
