Title: A cycle-based formulation and valid inequalities for DC power transmission problems with switchingSpeaker: Prof. Jeff LinderothAffiliation: Departments of Industrial and Systems Engineering and Computer Sciences (by courtesy) - University of Wisconsin-MadisonLocation: LT 145 Huxley BuildingTime: 3:00pmAbstract. It is well-known that optimizing network topology by switching on and off transmission lines improves the efficiency of... Read more »

Title: A bilevel programming problem occurring in smart gridsSpeaker: Prof. Leo LibertiAffiliation: Ecole Polytechnique ParisLocation: CPSE seminar room (C615 Roderic Hill)Time: 11:00amAbstract. A key property to define a power grid "smart" is its real-time, fine-grained monitoring capabilities. For this reason, a variety of monitoring equipment must be installed on the grid. We look at the... Read more »

Title: Computational Progress in Linear and Mixed Integer ProgrammingSpeaker: Dr. Robert BixbyAffiliation: GurobiLocation: CPSE seminar room (C615 Roderic Hill)Time: 11:00amAbstract. We will look at the progress in linear and mixed-integer programming software over the last 25 years. As a result of this progress, modern linear programming codes are now capable of robustly and efficiently solving... Read more »

Title: Estimating variance matricesSpeaker: Prof. Karim Abadir Affiliation: Imperial College Business SchoolLocation: Room 218 Huxley BuildingTime: 2:00pmAbstract.  This talk introduces a new method for estimating variance matrices. Starting from the orthogonal decomposition of the sample variance matrix, we exploit the fact that orthogonal matrices are never ill-conditioned and therefore focus on improving the estimation...
