convergence rate

[Hamide Zebardast]

Hi,

I compare RTR with RLBFGS method based on run time and number of iterations to converge with same criteria. The required iterations of the RTR is less, but it takes much time than RLBFGS. I can't analyze which one is faster. Would you please help me? 

Best,

In what sense?

From your message, it seems that if you care about computation time, then RLBFGS is faster for your application.
