Artists and scientists alike share a fascination for cyclic phenomena (also called strange loops), such as Escher’s drawings, Shepard’s musical scale, Condorcet’s voting paradox (inspiring Arrow’s impossibility theorem), the liar paradox,  Gödel’s incompleteness theorem, the Rock-Paper-Scissors children game, to name but a few.

In this lecture, we study cyclic phenomena associated with the winning probably relation of a random vector. We briefly introduce the cycle-transitivity framework, ideally suited for characterizing the transitivity of reciprocal relations, a generalization of crisp complete relations encompassing winning probability relations. Focusing on winning probability relations, we lay bare the link with the underlying dependence structure, and complement elegant theoretical results with remarkable observations made through massive computation involving all 9.30 E+10 sets of 4 dice with 6 faces (independent random variables), and all 1 104 891 746 non-isomorphic posets of 12 elements (intricately dependent random variables). Throughout, we point out connections with species competition, environmetrics and chemometrics, economics and finance, and machine learning.

Since most attention so far was limited to cycles of length three, we initiate the study of cycles of length four, introducing the Rock-Paper-Scissors-Lizard metaphor. Although the picture is still far from complete, it already offers some interesting insights and challenging open problems.


De Baets holds an M.Sc. degree in Mathematics (1988), a Postgraduate degree in Knowledge Technology (1991) and a Ph.D. degree in Mathematics (1995). He is a Full Professor (2008) in Applied Mathematics at Ghent University, Belgium, where he is leading the research unit Knowledge-based Systems (KERMIT, 2000) at the Faculty of Bioscience Engineering. He is an affiliated professor (2009) at the Anton de Kom Universiteit (Suriname) and an Honorary Professor (2006) of Budapest Tech (Hungary). He was a Government of Canada Awardholder (1988-89) at the Intelligent Systems Research Laboratory of the University of Saskatchewan.  He was elected Fellow of the International Fuzzy Systems Association in 2011 and has been nominated for the 2012 Ghent University Prometheus Award for Research.

KERMIT is an interdisciplinary team of (bio-)engineers, computer scientists and mathematicians.  Its current activities consist of three interwoven threads: knowledge-based, predictive and spatio-temporal modelling. B. De Baets has acted as supervisor of 44 Ph.D. students. At present, numerous Ph.D. students are involved in the research activities of KERMIT, either in-house, through affiliations or in the framework of joint projects. Due to its unique position, KERMIT serves as an attraction pole for applications in the applied biological sciences.

The bibliography of B. De Baets comprises more than 350 publications in international peer-reviewed journals, 60 chapters in books and 270 contributions to proceedings of international conferences. He delivered over 200 lectures at conferences and research institutes. He has received several best paper awards (1994, 2006, 2007, 2009, 2010 and 2013). B. De Baets is co-editor-in-chief (2007) of Fuzzy Sets and Systems and member of the editorial board of several other journals.
