WebLine search is used to decide the step length along the direction computed by an optimization algorithm. The following Optim algorithms use line search: Accelerated … WebWe use L-BFGS for optimising the objective function. It is a first-order method and hence requires computing the gradient of the objective function. We do not derive and implement the gradient function manually here but instead …

WebOptim will default to using the Nelder-Mead method in the multivariate case, as we did not provide a gradient. This can also be explicitly specified using: ...
