A Unified Early Termination Technique for Primal-dual Algorithms in Mixed Integer Conic Programming
Yuwen Chen, Catherine Ning, Paul Goulart
We propose an early termination technique for mixed integer conic programming for use within branch-and-bound based solvers. Our approach generalizes previous early termination res…
