March 25, 2022 @ 11:45 am – 12:35 pm – Sam Burer, Ph.D. University of Iowa Title: Convexification for Non-Convex Mixed-Integer Quadratic Programming Abstract: Convexification is an important technique used for solving non-convex mixed-integer quadratic programs. We discuss three recent convexification results for nonconvex quadratic programming over: (i) bounded (x1,x2,x3) with x1*x2 = x3; (ii) continuous (x1,x2) and binary (y1,y2) such that (0,0) <= (x1,x2) […]
