[Insight-users] Why does LBFGSBOptimizer never invoke the metric components

[黄成]

Hi ITK users,

          There is a question which bothers me for a long time. Why does
LBFGSBOptimizer never invoke the metric components? For an example, in a
registration method, I set a metric
component("itkMattesMutualInformationImageToImageMetric", for an example)
and set the LBFGSBOptimizer as the optimizer. Then no matter where I insert
the break point in the metric, once the registration process starts, it
will never stop until the optimization process finishes. It looks like the
optimizer process never invoke any method in the metric component.
Shouldn't the optimizer should put the value of metric into consideration
at each step?
