Convergence Analysis of Dirichlet-Neumann and Neumann-Neumann Waveform Relaxation Algorithms for Optimal Control of a Subdiffusion Model
The paper investigates the convergence behavior of the Dirichlet-Neumann and Neumann-Neumann waveform relaxation algorithms for optimal control problems with a subdiffusion PDE as the constraint. The impact of the fractional order of the time derivative on the convergence rate of the algorithms is analyzed.
