bet体育Operations research deals with the application of advanced analytical methods to help make better decisions. It is often concerned with determining the maximum (of profit, performance, or yield) or minimum (of loss, risk, or cost) of some real-world objective. Mathematical optimization is one of the most important techniques to arrive at optimal or near-optimal solutions to complex decision-making problems. The Operation Research group at Shanghai Jiao Tong University focuses on nonlinear least squares, polynomial optimization, sparse optimization, PDE constrained optimization, convex optimization, multi-objective optimization, large scale computational optimization with applications in science and engineering, etc.
