    Global optimization of nonconvex problems with convex-transformable intermediates

    This paper addresses the global optimization of problems which contain convex-transformable functions. We present algorithms for identification of convex-transformable functions in general nonconvex problems, ...

    SDP-quality bounds via convex quadratic relaxations for global optimization of mixed-integer quadratic programs

    We consider the global optimization of nonconvex mixed-integer quadratic programs with linear equality constraints. In particular, we present a new class of convex quadratic relaxations which are derived via q...
