Nettet8. jan. 2015 · 4. Dunno about TNC, but for L-BFGS-B, "line search failed" means that the algorithm was unable to find a low point along a ray originating at the current point. One possible cause is that your objective function cannot be evaluated along the ray (i.e., returning infinity or not-a-number or something). My advice is to put in some debugging ... NettetThere are some methods that will incorporate line searches into methods whose iterates are not necessarily primal feasible. NettetIn calculus, Newton's method is an iterative method for finding the roots of a differentiable function F, which are solutions to the equation F (x) = 0. As such, Newton's method can be applied to the derivative f ′ of a twice-differentiable function f to find the roots of the derivative (solutions to f ′ (x) = 0 ), also known as the ... red barn academy
