Seminar by Prof. Boualem Djehiche

Seminar: Some aspects of time inconsistence in stochastic optimal control

  • Class schedule: October 13, 2015 from ​2:00pm to 3:00pm
  • Location: Building 9, Lecture Hall I Room 2322
  • Refreshments will be served @ 1:45 pm 

Time inconsistent performance criteria are natural in optimization problems in themes such as large scale cooperative multi-agent systems including the principle-multi-agent (leader-follower) problem​ and crowd dynamics, diffusion of energy or fluids in non-homogeneous media, risk management of uncertain environment such as risks in river and coastal hydrology due to climate changes etc.  I will comment on some challenges faced by modern optimization techniques when the performance  criteria are time-inconsistent.  I will show for example that time-inconsistency makes the Dynamic Programming Principle fail to hold even for the very simplest optimization problem and proposes a way to overcome this difficulty.
