==========================================================
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 from November 10 to 14,
2025. Previous editions took plance 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).
As in previous editions, the conference proceedings will be published in a
selected journal, Procedia Computer Science, and a special edition of
Discrete Applied Mathematics will be devoted to selected full papers after
the conference.
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.
- Applications: Mathematical programming, combinatorial optimization
applied to areas such as logistics, scheduling, resource allocation, and
other real-world problems.
