WebFeb 5, 2024 · 3. Optim is designed for vector problems and not scalar ones like in your example. You can adjust the example to be a vector-problem with one variable though: julia> using Optim julia> function g (x) # <- g accepts x as a vector return x [1]^2 end julia> x0 = [2.0] # <- Make this a vector 1-element Vector {Float64}: 2.0 julia> optimize (g, x0 ... WebApr 6, 2024 · Options to the inner optimizer, such as GradientDescent, or LBFGS, is passed via the keyword argument optimizer_o. To use box constraints with LBFGS, you can do the following. Note that this will calculate derivatives using finite differences. It tells Fminbox to run 10 outer iterations, and LBFGS to run 2 iterations for each time it is called.
