A Faster Small Treewidth SDP Solver

Gu, Yuzhou, Song, Zhao

Understand

Semidefinite programming is a fundamental tool in optimization and theoretical computer science.

  • It has been extensively used as a black-box for solving many problems, such as embedding, complexity, learning, and discrepancy.
  • One natural setting of semidefinite programming is the small treewidth setting.
  • The best previous SDP solver under small treewidth setting is due to Zhang-Lavaei '18, which takes $n^{1.5} \tau^{6.5}$ time.
