Surgery Scheduling in Flexible Operating Rooms by using a Convex Surrogate Model of Second-Stage Costs
Mohammed Majthoub Almoghrabi, Guillaume Sagnol
We study the elective surgery planning problem in a hospital with operation rooms shared by elective and emergency patients. This problem can be split in two distinct phases. First…
An unexpected connection between Bayes optimal designs and the Group Lasso
Guillaume Sagnol, Edouard Pauwels
We show that the -optimal design optimization problem over design points in is equivalent to minimizing a quadratic function plus a group lasso sparsity induc…
Approximation of a Maximum-Submodular-Coverage problem involving spectral functions, with application to Experimental Design
Guillaume Sagnol
We study a family of combinatorial optimization problems defined by a parameter , which involves spectral functions applied to positive semidefinite matrices, and has so…
A Class of Semidefinite Programs with rank-one solutions
Guillaume Sagnol
We show that a class of semidefinite programs (SDP) admits a solution that is a positive semidefinite matrix of rank at most , where is the rank of the matrix involved in th…
