A Framework for Coalgebraic Reward-Sensitive Bisimulation (Extended Version)

Pedro H. Azevedo de Amorim, Mayuko Kori, Koko Muroya

In this paper we present a framework for modelling \emph{reward-sensitive bisimulations}, that is, bisimulations that account for quantitative differences such as accumulated rewar…

A Critical Pair Enumeration Algorithm for String Diagram Rewriting

Anna Matsui, Innocent Obi, Guillaume Sabbagh +4

Critical pair analysis provides a convenient and computable criterion of confluence, which is a fundamental property in rewriting theory, for a wide variety of rewriting systems. B…

A Variety of Request-Response Specifications

Daichi Aiba, Masaki Waga, Hiroya Fujinami +6

We find, motivated by real-world applications, that the well-known request-response specification comes with multiple variations, and that these variations should be distinguished.…

Explicit Hopcroft's Trick in Categorical Partition Refinement

Takahiro Sanada, Ryota Kojima, Yuichi Komorida +2

Algorithms for partition refinement are actively studied for a variety of systems, often with the optimisation called Hopcroft's trick. However, the low-level description of those…

Transparent Synchronous Dataflow

Steven W. T. Cheung, Dan R. Ghica, Koko Muroya

Dataflow programming is a popular and convenient programming paradigm in systems modelling, optimisation, and machine learning. It has a number of advantages, for instance the lack…

A robust graph-based approach to observational equivalence

Dan R. Ghica, Koko Muroya, Todd Waugh Ambridge

We propose a new step-wise approach to proving observational equivalence, and in particular reasoning about fragility of observational equivalence. Our approach is based on what we…

The Dynamic Geometry of Interaction Machine: A Token-Guided Graph Rewriter

Koko Muroya, Dan R. Ghica

In implementing evaluation strategies of the lambda-calculus, both correctness and efficiency of implementation are valid concerns. While the notion of correctness is determined by…

Abductive functional programming, a semantic approach

Koko Muroya, Steven Cheung, Dan R. Ghica

We propose a call-by-value lambda calculus extended with a new construct inspired by abductive inference and motivated by the programming idioms of machine learning. Although synta…

The Dynamic Geometry of Interaction Machine: A Call-by-need Graph Rewriter

Koko Muroya, Dan R. Ghica

Girard's Geometry of Interaction (GoI), a semantics designed for linear logic proofs, has been also successfully applied to programming language semantics. One way is to use abstra…
