ACAC is an annual meeting in Athens aiming to bring together researchers working in all areas of the theory of algorithms and computational complexity. It serves as a lively forum for presenting research results that are in a preliminary stage or have been recently accepted / presented in some major conference. Contributions may appear, fully or partially, in informal electronic proceedings available only to the participants (subject to authors' approval). The language of the workshop is English.

Topics of interest

Include, but are not limited to:
  • Analysis of Algorithms
  • Randomized and Approximation Algorithms
  • Computational Complexity
  • Data Structures
  • Cryptography
  • Graph Theory
  • Algorithmic Game Theory
  • Computational Geometry
  • Combinatorial Optimization
  • Algorithmic Algebra and Coding Theory
  • Theoretical Aspects of Databases
  • Computational Biology
  • Quantum Computing
  • Parallel and Distributed Computing
  • Machine Learning
  • Applications of Logic
Participants interested in giving a presentation should provide a tentative title and a short abstract, no later than August 11th. The organizers will make every possible effort so that all interested participants present their work (subject to schedule constraints).
