RUNNING THE L-BFGS-B CODE

it = iteration number

nf = number of function evaluations

nseg = number of segments explored during the Cauchy search

nact = number of active bounds at the generalized Cauchy point

sub = manner in which the subspace minimization terminated:

con = converged, bnd = a bound was reached

itls = number of iterations performed in the line search

stepl = step length used

tstep = norm of the displacement (total step)

projg = norm of the projected gradient

f = function value
