The problem of the axial vibration of a cantilever beam is investigated numerically. The mass distribution that minimizes the total mass for a given fundamental frequency constraint is determined using both the sequential gradient-restoration algorithm SGRA and an ad hoc modification of the modified quasilinearization algorithm MQA.
