Julia First Order Optimization
Open-sourced two Julia packages for separable optimization problems

Nicholas Moehle, Ellis Brown, Mykel Kochenderfer

Created a new Julia organization, JuliaFirstOrder, dedicated to first-order optimization methods. PiecewiseQuadratics.jl allows for the representation and manipulation of piecewise-quadratic functions, including the computation of the proximal operator and the convex envelope. SeparableOptimization.jl solves the problem of minimizing a sum of piecewise-quadratic functions subject to affine equality constraints by applying the Alternating Direction Method of Multipliers (ADMM). Presented at JuliaCon 2021.
