Not showing candidate solutions?

[naveenpalli]

Optim version 1.7.6/ Julia 1.9.2 on Windows 10. Running the basic rosenbrock function and I don't see the candidate solution values just the final objective value. Something missing in my setup?

julia> rosenbrock(x) = (1.0 - x[1])^2 + 100.0 * (x[2] - x[1]^2)^2 rosenbrock (generic function with 1 method)

julia> result = optimize(rosenbrock, zeros(2), BFGS())

• Status: success

• Candidate solution Final objective value: 5.471433e-17

• Found with Algorithm: BFGS

• Convergence measures |x - x'| = 3.47e-07 ≰ 0.0e+00 |x - x'|/|x'| = 3.47e-07 ≰ 0.0e+00 |f(x) - f(x')| = 6.59e-14 ≰ 0.0e+00 |f(x) - f(x')|/|f(x')| = 1.20e+03 ≰ 0.0e+00 |g(x)| = 2.33e-09 ≤ 1.0e-08

• Work counters Seconds run: 0 (vs limit Inf) Iterations: 16 f(x) calls: 53 ∇f(x) calls: 53

Looks like it is stored in result.minimizer as a Vector but not displayed. Closing this issue.

Note that this doesn't match the behavior in the documentation - might be worth updating or re-adding this to the output.
