Error? in OptimizationPackage/Optimization.md Documentation

[gbarz]

The code provided in the document examples below does not run successfully for me in Julia 1.10.
Instead the following is returned in both the unconstrained and constrained cases:

ERROR: UndefVarError: LBFGS not defined

In the unconstrained problem, if Optimization.LBFGS() is changed to just LBFGS(), it finds the solution. However, the constrained problem still returns the following:

ERROR: The algorithm LBFGS{Nothing, LineSearches.InitialStatic{Float64}, LineSearches.HagerZhang{Float64, Base.RefValue{Bool}}, Optim.var"#19#21"} does not support constraints. Either remove the cons function passed to OptimizationFunction or use a different algorithm.

Is there something else needed to get this to run successfully?

Unconstrained rosenbrock problem

using Optimization, Zygote

rosenbrock(x, p) = (p[1] - x[1])^2 + p[2] * (x[2] - x[1]^2)^2
x0 = zeros(2)
p = [1.0, 100.0]

optf = OptimizationFunction(rosenbrock, AutoZygote())
prob = Optimization.OptimizationProblem(optf, x0, p)
sol = solve(prob, Optimization.LBFGS())

With nonlinear and bounds constraints

function con2_c(res, x, p)
res .= [x[1]^2 + x[2]^2, (x[2] * sin(x[1]) + x[1]) - 5]
end

optf = OptimizationFunction(rosenbrock, AutoZygote(), cons = con2_c)
prob = OptimizationProblem(optf, x0, p, lcons = [1.0, -Inf],
ucons = [1.0, 0.0], lb = [-1.0, -1.0],
ub = [1.0, 1.0])
res = solve(prob, Optimization.LBFGS(), maxiters = 100)
