The VII Latin-American Algorithms, Graphs and Optimization Symposium (LAGOS) will be held on 22-26 April 2013 in Playa del Carmen, Mexico.

LAGOS is the union of two Latin American Conferences on these subjects: the Brazilian Symposium on Graphs Algorithms and Combinatorics (GRACO) and the Latin American Conference on Combinatorics, Graphs and Applications (LACGA) .

The previous editions were held in Fortaleza, Brazil (GRACO 2001), Santiago, Chile (LACGA 2004), Angra dos Reis, Brazil (GRACO 2005), Puerto Varas, Chile (LAGOS 2007), Gramado, Brazil (LAGOS 2009) and Bariloche, Argentina (LAGOS 2011). The proceedings of the accepted papers were published in Electronic Notes in Discrete Mathematics, and special editions of Discrete Applied Mathematics were dedicated to refereed full papers from these events.
