The Asynchronous PALM Algorithm for Nonsmooth Nonconvex Problems

  title={The Asynchronous PALM Algorithm for Nonsmooth Nonconvex Problems},
  author={Damek Davis},
We introduce the Asynchronous PALM algorithm, a new extension of the Proximal Alternating Linearized Minimization (PALM) algorithm for solving nonsmooth, nonconvex optimization problems. Like the PALM algorithm, each step of the Asynchronous PALM algorithm updates a single block of coordinates; but unlike the PALM algorithm, the Asynchronous PALM algorithm eliminates the need for sequential updates that occur one after the other. Instead, our new algorithm allows each of the coordinate blocks… CONTINUE READING
