Description
I'd like to do step-wise updates with BFGS, but the tf.while_loop in bfgs.minimize() does not allow this.
Would it be possible to make BFGS compatible with tf.train.Optimizer?

Research direction
Start by reading bfgs.minimize() and the tf.while_loop it uses, then compare the expected tf.train.Optimizer interface with the current BFGS behavior. Clarify how step-wise updates should work and define tests that demonstrate compatibility before making changes.
