Each year the MMOR Best Paper Award is bestowed on an excellent article published online in MMOR during the previous year. The list of past and current awardees is published on the MMOR web page. Candidates are nominated by the members of the MMOR editorial board, and the editorial board decides about the awardee(s).
In 2023 we published 32 papers online in MMOR. It is my great pleasure to announce that the 2023 MMOR Best Paper Award has been bestowed on the paper
A partial ellipsoidal approximation scheme for nonconvex homogeneous quadratic optimization with quadratic constraints
by Zhuoyi Xu, Linbin Li and Yong Xia (Fig. 1).
Abstract
An efficient partial ellipsoid approximation scheme is presented to find a \(1/\lceil m/2\rceil \)-approximation solution to the nonconvex homogeneous quadratic optimization with m convex quadratic constraints, where \(\lceil x\rceil \) is the smallest integer larger than or equal to x. If there is an additional nonconvex quadratic constraint beyond the m convex constraints, we can use the new scheme to find a 1/m-approximation solution.
