## We start very general.
##
## What type of problem is being solved? Classification
## is according to the geometry: 'Affine', 'Phase',
## 'Affine-sparsity', 'Custom'
'problem_family' : 'ART',
##==========================================
## Problem parameters
##==========================================
## What is the name of the data file?
'data_filename' : 'BLOCK_ART_data_processor',
'fanbeam' : 'no',
## What type of object are we working with?
## Options are: 'phase', 'real', 'nonnegative', 'complex'
'object' : 'complex',
## 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'
## 'convex'
'constraint' : 'convex',
## What type of measurements are we working with?
## Options are: 'single diffraction', 'diversity diffraction',
## 'ptychography', 'complex', and 'diversity affine'
'experiment' : 'convex',
## What are the dimensions of the measurements?
# given in the ART_data_processor
##==========================================
## Algorithm parameters
##==========================================
## Now set some algorithm parameters that the user should be
## able to control (without too much damage)
# Point to appropriate projectors.
'Prox1' : 'P_block_sequential_hyperplane',# projection onto support and nonnegativity constraint
'Prox2' : 'P_diag', # projection onto mask constraint
## Algorithm:
'algorithm' : 'QNAP', #'AP', 'Cimmino',
'numruns' : 1, # the only time this parameter will
# be different than 1 is when we are
# benchmarking, that is, when algorithm performance statistics
# are being generated for randomly generated problems/initial
# values etc.
## maximum number of iterations and tolerances
'MAXIT' : 40,
'TOL' : -1e-6,
## relaxaton parameters in RAAR, HPR and HAAR
'beta_0' : 1.0, # starting relaxation prameter (only used with
# HAAR, HPR and RAAR)
'beta_max' : 0.9, # maximum relaxation prameter (only used with
# HAAR, RAAR, and HPR)
'beta_switch' : 5, # 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' : 1e-15,
# 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.
'verbose' : 1, # options are 0 or 1
'graphics' : 1, # whether or not to display figures, options are 0 or 1.
# default is 1.
'anim' : 1, # whether or not to disaply ``real time" reconstructions
# options are 0=no, 1=yes, 2=make a movie
# default is 1. Animation does not currently work for reordered arrays
# below is just a hint of how one might make a movie of the reconstruction
# 'writerObj = VideoWriter('out.avi'), # Name it.
# 'writerObj.FrameRate = 25, # How many frames per second.
'animation' : 'ART_animation',
'graphics_display' : 'ART_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.
