SNESANDERSON#
Anderson Mixing nonlinear solver [And65], [BKST15]
Options Database Keys#
-snes_anderson_m - Number of stored previous solutions and residuals
-snes_anderson_beta - Anderson mixing parameter
-snes_anderson_restart_type - Type of restart (see
SNESNGMRES)-snes_anderson_restart_it - Number of iterations of restart conditions before restart
-snes_anderson_restart - Number of iterations before periodic restart
-snes_anderson_monitor - Prints relevant information about the ngmres iteration
Notes#
The Anderson Mixing method combines m previous solutions into a minimum-residual solution by solving a small linearized optimization problem at each iteration.
Very similar to the SNESNGMRES algorithm.
