Abstract :
The main aim of the present study is to propose a modified harmony search (MHS)
algorithm for size and shape optimization of structures. The standard harmony search (HS)
algorithm is conceptualized using the musical process of searching for a perfect state of the
harmony. It uses a stochastic random search instead of a gradient search. The proposed
MHS algorithm is designed based on elitism. In fact the MHS is a multi-staged version of
the HS and in each stage a new harmony memory is created using the information of the
previous stages. Numerical results reveal that the proposed algorithm is a powerful
optimization technique with improved exploitation characteristics compared with the
standard HS.
