Accelerating ADMM for efficient simulation and optimization

Juyong Zhang, Yue Peng, Wenqing Ouyang, Bailin Deng The alternating direction method of multipliers (ADMM) is a popular approach for solving optimization problems that are potentially non-smooth and with hard constraints. It has been applied to various computer graphics applications, … Continue reading
