*Further Information*

*This paper considers the high-dimensional table compression problem on balanced k -partite graph. The objective is to choose half of the vertices from each of the k -partite to maximize the total weight of edges connecting the chosen vertices. Our main contribution is a 0.8785-approximation algorithm for the high-dimensional table compression problem by introducing the α - i n d e p e n d e n t solutions through Lasserre semidefinite programming. This new algorithm improved two previous low-dimensional results, namely the 0.8731-approximation algorithm of Wu et al. for the one-dimensional case and the 0.6708-approximation of Xu and Du for the two-dimensional case. [Display omitted] • Present a 0.8785-approximation algorithm for high-dimensional table compression problem. • Obtain a group of independent optimal solutions through Lasserre hierarchy semidefinite programming. • The integer solutions to the original problem are obtained through deformed random hyperplane recognition.
