2nd Brazilian Workshop on Combinatorics

The Brazilian Workshop on Combinatorics is an event with a special focus on the areas of Extremal Combinatorics, Probabilistic Combinatorics, Graph Theory, Algorithms, and Combinatorial Optimization. Its main objective is to train undergraduate and graduate students to conduct research in combinatorics, to promote the field through high-level lectures, and to foster cooperation among students and Brazilian researchers in order to discuss methods and seek solutions to problems and conjectures in the area. The event aims to advance the state of the art and encourage scientific collaboration among peers in Brazil.
