Collaboration diagram for InnerStatsAccumulator< lbfgsb::LBFGSBStats >:

Class Members
nanoseconds	elapsed_time {}	Total elapsed time in the inner solver.
unsigned	iterations = 0	Total number of inner PANOC iterations.
real_t	final_ψ = 0	Final value of the smooth cost \( \psi(\hat x) \).
unsigned	lbfgs_rejected = 0	Total number of times that the L-BFGS update was rejected (i.e. it could have resulted in a non-positive definite Hessian estimate).
