SUMMARY:Power Seminar with Victor M. Zavala: Graph-Structured Optimization:
Properties\, Algorithms\, and Software - 3043 ECpE Bldg Addition - Sep 26
\, 2023 13:10
DESCRIPTION:Title: Graph-Structured Optimization: Properties\, Algorithms\,
and Software\n\nAbstract: We study properties for nonlinear optimization
problems whose structures are induced by graphs (collections of nodes conn
ected by edges). These problems arise in many applications such as dynamic
optimization (graph is a line)\, stochastic optimization (graph is a tree
)\, optimization with partial differential equations (graph is a mesh)\, a
nd network optimization (graph is the network). Specifically\, we introduc
e a fundamental property for graph-structured problems that we call “exp
onential decay of sensitivity.” This property states that\, for a given
pair of nodes\, the sensitivity of the solution at one node against a pert
urbation at the other node decays exponentially with respect to the distan
ce between the nodes. We discuss how this property provides new and intere
sting insights on how disturbances propagate through the structure of comp
lex systems and on what factors influence such propagation (e.g.\, control
lability and flexibility). We also show how this sensitivity property en
ables the design of new decomposition and approximation algorithms that ca
n tackle problems of unprecedented complexity. In addition\, we discuss ho
w to implement graph-structured problems in the Julia programming language
and how we use these capabilities to tackle diverse problems arising in e
nergy systems (e.g.\, power systems\, natural gas networks\, and HVAC).\n\
