Listing 2's implementation runs in o (n) time. I won't prove this, but the running time of Listing 1's naive, recursive implementation is exponential in n.
This method converted the S-N curve of material into the S-N curve of the construction member so that it made the computation more closely to the practical service life of the construction member.
Main characteristics of statistical accuracy for P-S-N curves are analyzed and the method for mean square error of P-S-N curves parameters by computer simulation is brought forward.
