Detailed Description

This is a simple track class for getting statistics about a solved (or not solved) NLP.

When output_final(...) is called the output stream will have the following written to it:

{verbatim} status = solved; # solved, except, max_iter, max_run_time niter = 10; # Number of rSQP iterations nfunc = 15; # max( number f(x) evals, number c(x) evals ) ngrad = 13; # max( number Gf(x) evals, number Gc(x) evals ) CPU = 0.50; # Number of CPU seconds total obj_func = 1.046e-2; # Objective function value f(x) at final point feas_kkt_err = 2.457e-10; # Feasibility error at final point (scaled ||c(x)||inf) opt_kkt_err = 4.568e-7; # Optimality error at final point (scaled ||rGL||inf) nact = 40; # Number of total active constraints at the final point nbasis_change = 1; # Number of basis changes nquasi_newton = 6; # Number of quasi-newton updates {verbatim}

Any statistic that is not known will be given the value '-'. If the returned status is 'execpt' then some exception was thrown or some other error occured so current information may not be available. In this case every effort is made to fill the rest of the information from prior iterations. The names of these fields will not change and the 'stat = value; # comment' format can be counted. However, the spacing and the precision of the numbers may be different from what is shown above.
