Recently, a popular metaheuristic algorithm called Harmony Search, conceptualized using the musical process of searching for a perfect state of harmony is undergoing faster developments. In this paper, a new variant of harmony search called Dynamic Hybrid Harmony Search algorithm (DHHS) is proposed. The novelty introduced in this algorithm is the division of the whole population into few sets of smaller populations/ groups within which the harmony improvisation occurs, before they are regrouped for a new better search. The intensification mechanism is improved by adding a customized neighborhood search algorithm. This proposed algorithm is applied to a combinatorial problem namely lay-up sequence optimisation of laminate composite stiffened cylinder. The results of the numerical studies prove that the proposed algorithm is efficient in handling the design of layup sequence problem.
