The ACM-SIAM Symposium on Discrete Algorithms is the leading conference on the design and analysis of discrete algorithms and data structures, covering combinatorial optimisation, graph algorithms, computational geometry, randomised and approximation algorithms, and the algorithmic side of machine learning. It suits researchers whose contribution is an algorithm with a proof of its behaviour; implementation is not expected, though the co-located ALENEX symposium exists for experimental algorithmics. Ranked A* by CORE, with an acceptance rate of 29.3% in 2025, high for its rank and a reflection of a large programme rather than low selectivity. Jointly sponsored by ACM SIGACT and SIAM, and co-located with ALENEX and SOSA.
