The Workshop on Future Research on Combinatorial Optimization (FRICO) is a conference with a 20-year-long history originating in Cologne. It aims at bringing together young researchers in the fields of integer and combinatorial optimization, OR, graph theory, and other related fields. The conference is characterized by its unconstrained nature that gives room for presentations of finished and on-going projects by early-caeer researchers. Since FRICO is organized solely by PhD students, a casual and engaging atmosphere is the trademark of the workshop. Every attendant of the conference also gives a presentation to establish a high level of interaction and creativity.
