Sparse Semidefinite Programs with Guaranteed Near-Linear Time Complexity via Dualized Clique Tree Conversion [article]

Richard Y. Zhang, Javad Lavaei
2020 arXiv   pre-print
Assuming that ω≪ n, we prove that the per-iteration cost of an interior-point method is linear O(n) time and memory, so an ϵ-accurate and ϵ-feasible iterate is obtained after O(√(n)log(1/ϵ)) iterations  ...  We consider two classes of semidefinite programs with favorable sparsity patterns that encompass the MAXCUT and MAX k-CUT relaxations, the Lovasz Theta problem, and the AC optimal power flow relaxation  ...  Our first main result guarantees these complexity figures for a class of semidefinite programs that we call partially separable semidefinite programs.  ...

Using Algebraic Properties of Minimal Idempotents for Exhaustive Computer Generation of Association Schemes

K. Coolsaet, J. Degraer
2008 Electronic Journal of Combinatorics  
Central to our success is the use of two algebraic constraints based on properties of the minimal idempotents $E_{i}$ of these association schemes : the fact that they are positive semidefinite and that  ...  Incorporating these constraints into an actual isomorph-free exhaustive generation algorithm turns out to be somewhat complicated in practice.  ...  A less accurate implementation of Algorithm 2 simply results in a less efficient generation program.  ...
