Dear all

When I used the method, L-BFGS-B, in OPTIM, I've got the following message.

[1] 0.176166426835580

[1] 1322.17600079332

function gradient 
       8        8 

[1] 0


[1,] 46300.3853279247


First, what does that message, "CONVERGENCE: REL_REDUCTION_OF_F <=
FACTR*EPSMCH",  mean? and I am wondering if the estimates are reliable.

Any comments will be greatly appreciated.
