The ACM Symposium on Theory of Computing (STOC) includes topics of interest such as: algorithms and data structures, computational complexity, cryptography, privacy, computational geometry, algorithmic graph theory and combinatorics, optimization, randomness in computing, approximation algorithms, parallel and distributed computation, machine learning, applications of logic, algorithmic algebra and coding theory, computational biology, computational game theory, quantum computing, and theoretical aspects of areas such as robotics, databases, information retrieval, and networks. Papers that broaden the reach of theory, or raise important problems that can benefit from theoretical investigation and analysis, are encouraged.
