Boukouvala, Fani (ed.); Gounaris, Chrysanthos E. (ed.) A preface to the special issue in memory of Professor Christodoulos A. Floudas (1959–2016). (English) Zbl 1434.01028 Optim. Lett. 14, No. 4, 797-800 (2020). From the text: This special issue marks three years after the unexpected and devastating passing of Professor Christodoulos (Chris) A. Floudas, an extraordinary scholar who has since been sorely missed by the Process Systems Engineering community as well as the broader world of Mathematical Optimization. Chris Floudas was the Stephen C. Macaleer ’63 Professor in Engineering and Applied Science at Princeton University, where he served as faculty for three decades. Later in his life, Chris joined Texas A&M University as the Director of the Texas A&M Energy Institute and the Erle Nye ’59 Chair Professor for Engineering Excellence.
