Trace-Based Coinductive Operational Semantics for While
We present four coinductive operational semantics for the While language accounting for both terminating and non-terminating program runs: big-step and small-step relational semant...

LP with Flexible Grouping and Aggregates Using Modes
We propose a new grouping operator for logic programs based on the group_by operator of SQL. The novelty of our proposal lies in the use of modes, which allows us to relax some rat...

Modularity, Product Innovation, and Consumer Satisfaction: An Agent-Based Approach
Abstract. The importance of modularity in product innovation is analyzed in this paper. Through simulations with an agent-based modular economic model, we examine the significance...

On Observing Dynamic Prioritised Actions in SOC
We study the impact on observational semantics for SOC of priority mechanisms which combine dynamic priority with local pre-emption. We define manageable notions of strong and wea...

When are Two Rewrite Systems More than None?
It is important for programs to have modular correctness properties. We look at non-deterministic programs expressed as termrewriting systems which compute normal forms of input t...
