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

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.
