## We start very general.
##==========================================
## Problem parameters
##==========================================
## What is the name of the data file?
'data_filename' : 'Goettingen_data_processor',
## What type of object are we working with?
## Options are: 'phase', 'real', 'nonnegative', 'complex'
'object' : 'nonnegative',
## What type of constraints do we have?
## Options are: 'support only', 'real and support', 'nonnegative and support',
## 'amplitude only', 'sparse real', 'sparse complex', and 'hybrid'
'constraint' : 'nonnegative and support',
## What type of measurements are we working with?
## Options are: 'single diffraction', 'diversity diffraction',
## 'ptychography', and 'complex'
'experiment' : 'CDI',
## Next we move to things that most of our users will know
## better than we will. Some of these may be overwritten in the
##data processor file which the user will most likely write.
## Are the measurements in the far field or near field?
## Options are: 'far field' or 'near field',
'distance' : 'far field',
'farfield':1,
## What are the dimensions of the measurements?
'Nx' : 128,
'Ny' : 128,
'magn': 1,
## What are the noise characteristics (Poisson or Gaussian)?
'noise':'false', # experimental data...organically noisy
##==========================================
## Algorithm parameters
##==========================================
## Now set some algorithm parameters that the user should be
## able to control (without too much damage)
## Algorithm:
'method' : 'AvP', # used to be 'Projection',
'numruns':1, # the only time this parameter will
# be different than 1 is when we are
# benchmarking...not something a normal user
# would be doing.
'keep_log':0,
## The following are parameters specific to RAAR, HPR, and HAAR that the
## user should be able to set/modify. Surely
## there will be other algorithm specific parameters that a user might
## want to play with. Don't know how best
## to do this. Thinking of a GUI interface, we could hard code all the
## parameters the user might encounter and have the menu options change
## depending on the value of the prbl.method field.
## do different things depending on the chosen algorithm:
'problem_family' : 'Phase',
## maximum number of iterations and tolerances
'MAXIT' : 6000,
'TOL' : 1e-8,
## relaxaton parameters in RAAR, HPR and HAAR
'beta_0' : 0.5 , # starting relaxation prameter (only used with
# HAAR, HPR and RAAR)
'beta_max' :0.50 , # maximum relaxation prameter (only used with
# HAAR, RAAR, and HPR)
'beta_switch' : 30 , # iteration at which beta moves from beta_0 -> beta_max
## parameter for the data regularization
## need to discuss how/whether the user should
## put in information about the noise
'data_ball' : 999826e-30,
# prbl.data_ball : 9998261e-0,
# the above is the percentage of the gap
# between the measured data and the
# initial guess satisfying the
# qualitative constraints. For a number
# very close to one, the gap is not expected
# to improve much. For a number closer to 0
# the gap is expected to improve a lot.
# Ultimately the size of the gap depends
# on the inconsistency of the measurement model
# with the qualitative constraints.
##==========================================
## parameters for plotting and diagnostics
##==========================================
'diagnostic' : True ,# to stop the diagnostics, just comment this field out.
'rotate': False,
'iterate_monitor':'feasibility_iterate_monitor',
'verbose' : 1, # options are 0 or 1
'graphics' : 1, # whether or not to display figures, options are 0 or 1.
# : default is 1.
'anim' : 0, # whether or not to disaply ``real time" reconstructions
# options are 0:no, 1:yes, 2:make a movie
# default is 1.
'graphics_display' : 'Phase_graphics',# unless specified, a default
# plotting subroutine will generate
# the graphics. Otherwise, the user
# can write their own plotting subroutine
##======================================================================
## Technical/software specific parameters
##======================================================================
## Given the parameter values above, the following technical/algorithmic
## parameters are automatically set. The user does not need to know
## about these details, and so probably these parameters should be set in
#a module one level below this one.
