Advanced control of algorithmic options for CARP and CBASS.
The clustRviz_reset_options function returns options to "factory-fresh"
settings.

The following options can be set by name:
epsilon The initial step size (fixed during the "burn-in" period)
stopping_threshold: Stopping threshold to use for convex_clustering,
convex_biclustering, CARP(exact = TRUE),
and CBASS(exact = TRUE). By default,
this is set to 1e-10 - a very conservative
threshold: making it larger can significantly
improve performance
max_iter An integer: the maximum number of iterations to perform
max_inner_iter An integer: the maximum number of iterations for
the iterative solvers to perform at a single
value of \(\lambda\).
burn_in An integer: the number of initial iterations at a fixed
(small) value of \(\gamma\)
viz_initial_step The initial (large) step size used in back-tracking
(CARP-VIZ and CBASS-VIZ) algorithms.
viz_small_step The secondary (small) step size used in back-tracking
(CARP-VIZ and CBASS-VIZ) algorithms.
viz_max_inner_iter The maximum number of iterations to perform
in the inner loop of back-tracking (CARP-VIZ
and CBASS-VIZ) algorithms.
keep CARP and CBASS keep every
keep-th iteration even if no fusions are detected.
Increasing this parameter may improve performance, at
the expense of returning a finer grid.
rho For advanced users only (not advisable to change): the penalty
parameter used for the augmented Lagrangian.
keep_debug_info: Should additional debug info (currently only the V-path)
be kept?
