Arguments

max_it

maximum number of iterations.

tightening

how to make inner iterations more precise as the algorithm approaches a local minimum.

tightening_steps

for adaptive tightening strategy, how often to tighten until the desired tolerance is attained.

en_algorithm_opts

options for the inner LS-EN algorithm. See en_algorithm_options for details.

Value

options for the MM algorithm.
