This past Friday, we were delighted to be able to host Mr. Basilio Gentile of ETH in Zurich, Switzerland in our INFORMS Speaker Series.
His talk was on: Distributed Dynamics to Achieve Location Equilibrium.
His presentation was on recent work that he has done with with Dario Paccagnan, Bolutife Ogunsola, and Professor John Lygeros. That work was inspired by my work on migration equilibrium and variational inequalities, which is gratifying. I had blogged about migration equilibrium because of the refugee crises.
Basilio described an elegant framework for what he is calling location equilibrium, consisting of a model and a novel algorithm, supported by theory. The framework has potentially a wide range of exciting potential applications. Location equilibrium can be viewed as a type of migration equilibrium in which the costs of migration between locations are not flow-dependent, as in my work with collaborators, but are fixed. One is interested in determining, given a fixed population in the economy or network, the equilibrium population distributions at the nodes. He mentioned some very nonobvious interesting applications from taxi distributions in Hong Kong to computer server allocations.
important equilibrium concepts from Wardrop to Nash and their linkages to location and migration equilibrium! It was terrific that some of the graduate students who had taken my variational inequalities, game theory, and networks seminar got to hear more on the subject and from a speaker from Switzerland. Basilio is originally from Italy and has met my wonderful collaborator and Supernetwork Center Associate, Professor Patrizia Daniele.
After the talk, joining us for lunch at the University Club were: Professor Eric Gonzales, one of my colleagues in Transportation at UMass Amherst, who is a UC Berkeley PhD, and two UMass Amherst INFORMS Student Chapter Officers: Pritha Dutta, who is the President, and Ekin Koker, who is the Vice President and Webmaster.
We thank Basilio Gentile for coming to speak at the University of Massachusetts Amherst!
