The radius of the outer Dikin ellipsoid of the intersection of m ellipsoids due to Fu et al. (J. Comb. Optim., 2, 29-50, 1998) is corrected from m to \(\sqrt{m^2+m}\). The approximation bound for the general convex quadratic constrained nonconvex quadratic program is correspondingly corrected.

评论“二次规划的近似算法”

由于 Fu 等人的m椭球相交的外部 Dikin 椭球的半径。(J. Comb. Optim., 2, 29-50, 1998) 从m更正为\(\sqrt{m^2+m}\)。对一般凸二次约束非凸二次规划的逼近界进行了相应修正。
