pkofod·7y ago·June 5, 2018New input sequence and better support of Real subtypes
pkofod·8y ago·May 26, 2018anriseth·8y ago·May 18, 2018anriseth·8y ago·April 26, 2018Static no longer takes the `alpha` and `scaled` arguments, but instead takes the step provided at each call to the line search. The old functionality can still be accessed by combining `Static` with `InitialStatic` for the initial step guess.
anriseth·8y ago·April 25, 2018pkofod·8y ago·April 15, 2018pkofod·8y ago·March 31, 2018This major version of LineSearches introduces a slim-lined internal machinery of LineSearches.jl. The actual line searches no longer depend on `AbstractObjective`s from NLSolversBase.jl, but only on univariate functions for phi, the derivative of phi and a composite version. This version is breaking, as it removes some of the Optim specific things such as LineSearchResults from the package. This makes the individual line searchers more stand-alone in nature. The initial guesses are still tied to the JuliaNLSolvers setup.
pkofod·8y ago·January 22, 2018Allow AbstractArray instead of Array to support more input types.
anriseth·8y ago·January 17, 2018Use vecnorm instead of norm on gradients and decision vectors. Fixes problems with optimization with arbitrary inputs (3-dimensional arrays etc.)
