Separable QCQPs and Their Exact SDP Relaxations

Masakazu Kojima, Sunyoung Kim, Naohiko Arima

This paper studies exact semidefinite programming relaxations (SDPRs) for separable quadratically constrained quadratic programs (QCQPs). We consider the construction of a larger s…

Extending Exact Convex Relaxations of Quadratically Constrained Quadratic Programs

Masakazu Kojima, Sunyoung Kim, Naohiko Arima

A convex relaxation of a quadratically constrained quadratic program (QCQP) is called exact if it has a rank-1 optimal solution that corresponds to an optimal solution of the QCQ…

Constructing QCQP Instances Equivalent to Their SDP Relaxations

Masakazu Kojima, Naohiko Arima, Sunyoung Kim

General quadratically constrained quadratic programs (QCQPs) are challenging to solve as they are known to be NP-hard. A popular approach to approximating QCQP solutions is to use…
