Hi,
I use the function nlminb to maximize a function and got convergence with the
message false-convergence. I know the reason may be the gradient $B"`(Bf(x)
may be computed incorrectly, the other stopping tolerances may be too tight, or
either f or $B"`(Bf may be discontinuous near the current iterate x.
However, I want to know how to modify the program after this problem occurs.
Thanks very much.
