The Douglas-Rachford Algorithm Converges Only Weakly.
SIAM journal on control and optimization(2020)
摘要
We show that the weak convergence of the Douglas-Rachford algorithm for finding a zero of the sum of two maximally monotone operators cannot be improved to strong convergence. Likewise, we show that strong convergence can fail for the method of partial inverses.
