the absolute tolerance on the duality gap if reduced precision, parameter abstol_inacc
the relative tolerance on the duality gap if reduced precision, parameter reltol_inacc
the maximum number of iterations for ecos, parameter maxit
the maximum number of branch and bound iterations (mixed integer problems only), parameter mi_max_iters
the integer tolerence (mixed integer problems only), parameter mi_int_tol
the absolute tolerance between upper and lower bounds (mixed integer problems only), parameter mi_abs_eps

verbosity level, parameter verbose
the maximum number of iterations for ecos, default 100L
the tolerance on the primal and dual residual, default 1e-8
the relative tolerance on the duality gap, default 1e-8
the absolute tolerance on the duality gap, default 1e-8

the absolute tolerance on the duality gap if reduced precision, default 5e-5
the relative tolerance on the duality gap if reduced precision, default 5e-5
verbosity level, default 0L. A verbosity level of 1L will show more detail, but clutter session transcript.
