The purpose of this survey is to serve both as a gentle introduction and a coherent overview of state-of-the-art Frank--Wolfe algorithms, also called conditional gradient algorithms, for function minimization. These algorithms are especially useful in convex optimization when linear optimization is cheaper than projections. The selection of the material has been guided by the principle of highlighting crucial ideas as well as presenting new approaches that we believe might become important in the future, with ample citations even of old works imperative in the development of newer methods. Yet, our selection is sometimes biased, and need not reflect consensus of the research community, and we have certainly missed recent important contributions. After all the research area of Frank--Wolfe is very active, making it a moving target. We apologize sincerely in advance for any such distortions and we fully acknowledge: We stand on the shoulder of giants.

  1. Lions and Muons: Optimization via Stochastic Frank-Wolfe under Heavy-Tailed Noise

    math.OC 2025-06 reject novelty 6.0 of 10

    Lion and Muon with weight decay are shown to be instances of one stochastic Frank-Wolfe algorithm, and clipped and variance-reduced variants get the first high-probability convergence rates for nonconvex Frank-Wolfe u...

  2. Secant Line Search for Frank-Wolfe Algorithms

    math.OC 2025-01 reject novelty 6.0 of 10

    A secant-method line search computes near-exact Frank-Wolfe step sizes in few gradient evaluations, claiming to match exact line search in theory and practice.

  3. Minimum enclosing Bregman balls made easy

    cs.IT 2026-07 accept novelty 5.0 of 10

    Left Bregman MEBs equal power MEBs on dual Laguerre points; Frank-Wolfe power approximation recovers the 2005 Bregman algorithm, and Bregman liftings equal paraboloid liftings.

  4. A Unified Toolbox for Multipartite Entanglement Certification

    quant-ph 2025-07 reject novelty 5.0 of 10

    Conditional gradient methods can certify multipartite entanglement heuristically and rigorously, with improved noise robustness bounds for Horodecki states.

  5. A Fully Adaptive Frank-Wolfe Algorithm for Relatively Smooth Problems and Its Application to Centralized Distributed Optimization

    math.OC 2025-07 reject novelty 5.0 of 10

    A Frank-Wolfe method that adapts both the smoothness constant and the triangle-scaling exponent achieves sublinear convergence and a tolerance-dependent linear rate, with a centralized distributed optimization application.

  6. Observing High-dimensional Bell Inequality Violations using Multi-Outcome Spectral Measurements

    quant-ph 2025-06 conditional novelty 5.0 of 10

    Measuring only the joint spectral intensity of a time-bin entangled two-photon state suffices to violate the CGLMP Bell inequality up to dimension 8 using genuinely multi-outcome measurements.
