WebPreliminary computational studies in a MATLAB environment applying pure Frank-Wolfe, conjugate direction Frank-Wolfe (CFW), bi-conjugate Frank- Wolfe (BFW), and "par-tanized" Frank-Wolfe methods to some classical Traffic Assignment Problems show that CFW and BFW compare favorably to the other methods. WebMar 15, 2024 · In this paper, we present a random perturbation of Frank-Wolfe method (a.k.a. Conditional gradient method) for solving nonconvex differentiable programming under linear differentiable constraints. WebThe Frank-Wolfe (FW) method (Frank & Wolfe, 1956) was originally suggested for quadratic programming problems, but the original paper also noted that it could be applied to linearly constrained convex programs. The main usage of the FW method has been in routing problems in the telecom and traﬃc areas, where it is usually attributed to (Fratta, metaverse consulting firms
