Hi, my call of optim() with the L-BFGS-B method ended with the following error message: ERROR: ABNORMAL_TERMINATION_IN_LNSRCH
Further tracing shows: Line search cannot locate an adequate point after 20 function and gradient evaluations final value 0.086627 stopped after 7 iterations Could someone pls tell me whether it is possible to increase the limit of 20 evaluations? Is it even worth doing so? My function(s) to be minimized are polynomial functions of tens of variables - let say 10 - 60 variables, all of them constrained to the (0,1) interval. Is it even possible and meaningfull to attempt such minimization? (Suppose I have good starting values.)
