With 64 basis functions,m= 32, and a partition of into 32 segments,n= 32, PDS converged from a random starting point in 52 iterations to a tolerance of le-6. Thirtynine minutes (wall clock) elapsed during its 68935 function evaluations. It produced an optimal that is close to a constant value of 11195. The two figures on the following page depict the associated spectrum. The movie depicts the optimally damped beams rapid return to rest after being subjected to an initial disturbance.
