  • Optimization and Machine Learning Seminar is a four-week seminar organized by CoReLab at NTUA from 11 Dec 2018 to 16 Jan 2019. The goal of this seminar is to introduce the basic concepts of machine learning and convex optimization.

  • FCT 2021 - 23rd International Symposium on Fundamentals of Computation Theory
    The Symposium on Fundamentals of Computation Theory was established in 1977 to serve as a forum for researchers interested in all aspects of theoretical computer science, and in particular algorithms, complexity, formal and logical methods. It is a biennial series of conferences.
    FCT 2019 will take place in Copenhagen, Denmark, August 11-14, 2019.
    FCT 2021 will take place in Athens, Greece, September 5-8, 2021, hosted by the Computation and Reasoning Laboratory (CoReLab) and the School of Electrical and Computer Engineering of the National Technical University of Athens.

  • Athens Colloquium on Algorithms and Complexity 2018 (ACAC18)
    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.
    ACAC18 will take place on Thursday-Friday, 23-24 August, at the Multimedia Center of the Central Library of NTUA.

  • Athecrypt 2018
    Athecrypt, the Athens Theoretical Cryptography meeting is an annual event. Its purpose is to give the opportunity to graduate students in Greece to observe talks of researchers from all areas of Cryptography. In 2018, it took place on Tuesday, January 9, at the Multimedia Center of the Central Library of NTUA.
    The next event is scheduled for January 2019.
  • Lecture of Aristotelis Tsirigos, Associate Professor (NYU School of Medicine), Friday, September 29, 2017 at 15:30, NTUA Central Library (Multimedia amphitheater).
  • The 10th International Conference on Algorithms and Complexity (CIAC 2017) took place in Athens, Greece, on May 24-26, 2017. The International Conference on Algorithms and Complexity is intended to provide a forum for researchers working in all aspects of computational complexity and the use, design, analysis and experimentation of efficient algorithms and data structures.
