Title: Phase transitions: from physics to computer science


Speaker: Jean Barbier (Jean Barbier)

Abstract: Phase transitions happen in complex systems, systems made of
very manyinteracting entities, and correspond to a change of macroscopic
state of the system when some external control parameter is tuned. The
classical example are molecules of water globally changing from ice to
liquid to vapour (to plasma) as temperature increases. But in the past 50
years it has been realised that phase transitions are much more
«universal», in the sense that they also happen in systems that may a
priori be considered far from the realm of condensed matter physics:
neurosciences, biological systems, financial markets, but also in more
abstract «Information processing systems»: computer science and algorithms
for combinatorial optimisation, machine learning from data, or inference
of large signals hidden in noise. «No way
 Yes way!»
