[Insight-users] Why itk::LBFGSBOptimizer and itk::LBFGSOptimizer are classed as single-variant optimisers?

[Ali -]

Hi, 

The VNL wrappers itk::LBFGSBOptimizer and itk::LBFGSOptimizer are classified as single-variant optimiser, while being based on the quasi-Newton method, they are multi-variant optimisers by nature -- see http://www.alglib.net/optimization/ . Is this the ITK wrapper problem or a VNL issue?
