Unifying Farkas lemma and S-lemma: new theory and applications in nonquadratic nonconvex optimization
Meijia Yang, Yong Xia, Shu Wang
We unify nonlinear Farkas lemma and S-lemma to a generalized alternative theorem for nonlinear nonconvex system. It provides fruitful applications in globally solving nonconvex non…
Chebyshev Center of the Intersection of Balls: Complexity, Relaxation and Approximation
Yong Xia, Meijia Yang, Shu Wang
We study the n-dimensional problem of finding the smallest ball enclosing the intersection of p given balls, the so-called Chebyshev center problem (CCB). It is a minimax optimizat…
Approximation of the weighted maximin dispersion problem over Lp-ball: SDP relaxation is misleading
Zuping Wu, Yong Xia, Shu Wang
Consider the problem of finding a point in a unit -dimensional -ball () such that the minimum of the weighted Euclidean distance from given points is maximiz…
On the Ball-Constrained Weighted Maximin Dispersion Problem
Shu Wang, Yong Xia
The ball-constrained weighted maximin dispersion problem is to find a point in an -dimensional Euclidean ball such that the minimum of the weighted Euclidean di…
