SNESAnderson

Anderson Mixing method.

Options Database

-snes_anderson_m - Number of stored previous solutions and residuals
-snes_anderson_beta - Relaxation parameter; X_{update} = X + \beta F
-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.
