Harmony Search Methods for Multi-modal and Constrained Optimization - Music-Inspired Harmony Search Algorithm: Theory and Applications - page 50

6 Conclusions
In this chapter, we proposed and discussed two modified HS methods to deal with the
multi-modal and constrained optimization problems. In the first modified HS method,
a fish swarm-based technique is employed to maintain the diversity of the HM mem-
bers, which makes it a suitable candidate for the multi-modal problems. The second
modified HS method is capable of directly handling the constraints in the constrained
optimization problems. Several simulation examples have been employed to verify
the effectiveness of the proposed schemes. Compared with the original HS method,
better optimization results are acquired using our modified HS approaches. However,
some important theoretical issues, such as convergence analysis, need to be further
explored. We are also going to study how to apply these new methods in manipulating
more real-world problems.
