Mutation‐Guided Metamorphic Testing of Optimality in AI Planning

Software Testing, Verification and Reliability, Volume 35, Issue 1, January 2025.
Based on mutation adequacy test suite selection, this article proposes a novel metamorphic testing framework for detecting the lack of optimality in AI plannersg. ABSTRACT Autonomous systems such as space‐ or underwater‐exploration robots or elderly people assistance robots often include an artificial intelligence (AI) planner as a component.

Reinforcing Cloud Attack Tolerance on a Large Scale: Advanced Blockchain Technologies With Hierarchical Risk and Smart Contracts

IET Blockchain, Volume 5, Issue 1, January/December 2025.
We propose a blockchain‐based system to enhance cloud systems' resilience against distributed denial of service attacks. Our approach integrates a hierarchical risk‐based attack tolerance mechanism with smart contracts, dynamically estimating risks at local, cluster, and global levels using Dempster–Shafer theory. Simulations show improved availability,

Mobilising new frontiers in digital transformation research: A problematization review

Information Systems Journal, Volume 35, Issue 1, Page 97-139, January 2025.
Abstract In this paper, we mobilise new frontiers in digital transformation (DT) research by deconstructing the literature's underlying assumptions and analysing their correspondence with current theory. To do so, we conduct a problematization review across the fields of IS, strategy and entrepreneurship, organisation theory and management studies, to ...
