var i; sml; bfgs_calls; nfix; max_calls

sml = 1.e-4 % Gradient threshlod.

bfgs_calls = 1000 % Number of BFGS calls.

max_calls = 10000 % Max. calls to spend.

again:

loosall

nfix = 0

loop i from 1 to dim

if abs[grad[i]] <= sml then

fix (x.i)

nfix = nfix+1

end if

end loop

if nfix == dim then

display 'Gradient below threshold...'

loosall

finish

end if

bfgs (noc=bfgs_calls)

when pcount < max_calls just move to again

display 'We probably failed...'

end
