    Message Passing for Maximum Weight Independent Set by Sanghavi, Sujay, Shah, Devavrat, Willsky, Alan S.

    Published 2011
    “…We show that each fixed-point estimate of max product can be mapped in a natural way to an extreme point of the linear programming (LP) polytope associated with the MWIS problem. However, this extreme point may not be the one that maximizes the value of node weights; the particular extreme point at final convergence depends on the initialization of max product. …”

    New Theory and Algorithms for Convex Optimization with Non-Standard Structures by Zhao, Renbo

    Published 2023
    “…In the second chapter, we present and analyze a new away-step Frank-Wolfe method for the convex optimization problem min𝑥∈𝒳 𝑓(A𝑥) + ⟨𝑐, 𝑥⟩, where 𝑓 is a 𝜃-logarithmically-homogeneous self-concordant barrier, A is a linear operator, ⟨𝑐, ·⟩ is a linear function and 𝒳 is a nonempty polytope. We establish the global linear convergence rate of our Frank-Wolfe method in terms of both the objective gap and the Frank-Wolfe gap. …”

    Discrete–geometric functions associated to polyhedral cones and point sets by Wang, Xinli

    Published 2012
