epsa Absolute convergence tolerance (default 1e-6).
epsr Relative convergence tolerance (default 1e-5).
maxtime Maximum CPU seconds allowed (default -1, means no limit).
outlev Whether to chatter: 0 ==> no(default), 1 ==> yes.
threadingmode Threading mode for solvers with multithreading support:
-1 = solver decides (default)
0 = try parallel mode, if not available try concurrent mode

2 = try concurrent mode, if not available try parallel mode
3 = force concurrent mode.
threads Number of threads to be used (default -1, uses solver default).
wantsol Solution report without -AMPL: sum of
1 ==> write .sol file
2 ==> print primal variable values
4 ==> print dual variable values
8 ==> do not print solution message
