Convexification of mixed-integer quadratic optimization via decision diagrams
Soobin Choi, Salar Fattahi, Andres Gomez +2
We study mixed-integer quadratic optimization (MIQO) problems with indicator variables. We propose a unified framework, based on decision diagrams, that serves both to solve the as…

Rank-one convexification for quadratic optimization problems with step function penalties
Soobin Choi, Valentina Cepeda, Andres Gomez +1
We investigate convexification for convex quadratic optimization with step function penalties. Such problems can be cast as mixed-integer quadratic optimization problems, where bin…
