DESCRIPTION:Title: <a href="https://stable.researchseminars.org/talk/MathI
 CTPSeminars2020/2/">Phase transitions: from physics to computer science</a
 >\nby Jean Barbier (ICTP) as part of Basic Notions Seminar\n\nLecture held
  in zoom meeting.\n\nAbstract\nPhase transitions happen in complex systems
 \, systems made of very many interacting entities\, and correspond to a ch
 ange of macroscopic state of the system when some external control paramet
 er is tuned. The classical example are molecules of water globally changin
 g from ice to liquid to vapour (to plasma) as temperature increases. But i
 n the past 50 years it has been realised that phase transitions are much m
 ore «universal»\, in the sense that they also happen in systems that may
  a priori be considered far from the realm of condensed matter physics: ne
 urosciences\, biological systems\, financial markets\, but also in more ab
 stract «Information processing systems»: computer science and algorithms
  for combinatorial optimisation\, machine learning from data\, or inferenc
 e of large signals hidden in noise. «No way… Yes way!»\n
