About LAGOS 2025

The Latin American Algorithms, Graphs, and Optimization Symposium (LAGOS) is a biennial event that brings together researchers and practitioners from around the world. Since its inception in 2001, LAGOS has served as a key forum for the exchange of ideas and collaboration. It represents the merger of two Latin American conferences: the Brazilian Symposium on Graphs, Algorithms, and Combinatorics (GRACO) and the Latin American Conference on Combinatorics, Graphs, and Applications (LACGA).

LAGOS 2025 will be held in Buenos Aires, Argentina. Previous editions took place in Fortaleza, Brazil (2001), Santiago, Chile (2004), Angra dos Reis, Brazil (2005), Puerto Varas, Chile (2007), Gramado, Brazil (2009), Bariloche, Argentina (2011), Playa del Carmen, Mexico (2013), Fortaleza, Brazil (2015), Marseille, France (2017), Belo Horizonte, Brazil (2019), São Paulo, Brazil (2021), and Huatulco, Mexico (2023).

Scope and Topics

LAGOS 2025 invites submissions on a broad range of topics, including but not limited to:

• Algorithms and Complexity: Approximation algorithms, computational complexity, parallel and distributed algorithms, parameterized complexity, computational geometry, randomized algorithms.
• Operations Research and Optimization: Combinatorial optimization, integer programming, polyhedral combinatorics, heuristics and metaheuristics.
• Graph Theory: Cliques, independent and dominating sets, colorings, covering and packing, matchings, digraphs, graph algorithms, graphs and matrices, hypergraphs, perfect graphs, random graphs, structural characterization of graph classes.
