Information-theoretic inequalities play a fundamental role in numerous scientific and technological areas (e.g., estimation and communication theories, signal and information processing, quantum physics, …) as they generally express the impossibility to h... see more

An expanded version of Melanie Mitchell's Ulam Memorial Lectures introduces new readers to some of the core historical and current sites of interest and samples of the biographical and cultural history of the sciences of complexity. Likely to become an i... see more

The structure of system complexity is introduced; and the linked complexity of systems is determined according to it. 

This article discusses the ‘Lachmannian dilemma’: a theory about spontaneous orders requires methodological subjectivism and the complexity of the allocative problem. However, the formal representation of the economic problem in the economic theory of com... see more

The purpose of this study is to investigate the impact of manipulating the cognitive complexity of tasks on EFL learners’ narrative task performance in terms of complexity, accuracy, and fluency of their production. To this aim, by drawing upon Robinson’s... see more

We define space complexity classes in the framework of membrane computing, giving some initial results about their mutual relations and their connection with time complexity classes, and identifying some potentially interesting problems which require furt... see more

Tiling planar regions with dominoes is a classical problem, where the decision and counting problems are polynomial.  We prove a variety of hardness results (both NP- and #P-completeness) for different generalizations of dominoes in three and higher ... see more

Complex systems (CS) involve many elements that interact at different scales in time and space. The challenges in modeling CS led to the development of novel computational tools with applications in a wide range of scientific areas. The computational prob... see more
