class ptypy.engines.stochastic.SDRMixin(sigma, tau, beta_probe, beta_object)#

Bases: object

Defaults:

[sigma] default = 1 type = float lowlim = 0.0 help = Relaxed Fourier reflection parameter.

[tau] default = 1 type = float lowlim = 0.0 help = Relaxed modulus constraint parameter.

[beta_probe] default = 0.1 type = float lowlim = 0.0 help = Parameter for adjusting the step size of the probe update

[beta_object] default = 0.9 type = float lowlim = 0.0 help = Parameter for adjusting the step size of the object update
