Periodic Reporting for period 3 - TAMING (Taming non convexity?)
Reporting period: 2018-09-01 to 2019-08-31
"The Moment-SOS approach (or the Moment-SOS hierarchy) has been already considered a breakthrough in the field of optimization and more recently in Theoretical Computer Science (TCS). Indeed the TCS community calls the SOS-hierarchy (aka the ""Lasserre hierarchy"") a META algorithm as it applies ""canonically"" to most combinatorial optimization problems in graphs. In particular is is now recognized as a fundamental tool to prove/disprove Khot's celebrated ""Unique Games Conjecture"" (UGC) in TCS. One challenge is to make the moment-SOS approach scalable so as to potentially solve some large scale problems, and in particular the Optimum Power Flow problem (OPF) of strategic importance in the Management of Energy networks. Another challenge is to show that the moment-SOS approach can be applied in various other applications to provide better solutions than those provided
by other methods, e.g. in Control, Optimal Control and Robotics, in some inverse problems, in Statistics, Machine Learning. Therefore, and according to the accepted proposal TAMING, the research plan consists of mainly two types of research investigations: (I) Theoretical and algorithmic research on the moment–SOS approach, and (II) versatility and power of the moment-SOS approach."

I. The Lasserre-hierarchy adapted by Cedric Josz and D. Molzahn for solving some Optimum Power Flow problems (OPFs) with thousands variables is already considered a breakthrough in the management of Power Systems. It is not yet clear whether the alternative sparse version [2] of [1] will bring significant improvements. However for other large scale applications it could make a difference. It should be noted that the SOS-algorithm is also at the core of the 2018 ERC consolidator grant UTOPEST (of David Steurer, ETH, Zurich) and is called a meta-algorithm by the Theoretical Computer Science research community.
II. All contributions in II.1 -> II.5 describe a completely new methodology for difficult problems: (i) Optimal design for polynomial regression in Statistics, (ii) nonlinear hyperbolic PDE's, and (iii) the Christoffel
function for Statistics & Machine Learning should have a noticeable impact very soon. In recognition of the impact of this methodology:
