In this paper, we consider the problem of scheduling a set of jobs on two parallel machines to minimize the sum of completion times. Each job requires a setup which must be done by a single server. It is known that this problem is strongly NP-hard. We propose an improved harmony search algorithm. The performance of this algorithm is evaluated and compared with a pure simulated annealing algorit...

This study presents a cost minimization model for the design of water distribution networks. The model uses a recently developed harmony search optimization algorithm while satisfying all the design constraints. The harmony search algorithm mimics a jazz improvisation process in order to find better design solutions, in this case pipe diameters in a water distribution network. The model also in...

The objective of this paper is to present an optimal design for single-layer barrel vault frames via improved magnetic charged system search (IMCSS) and open application programming interface (OAPI). The IMCSS algorithm is utilized as the optimization algorithm and the OAPI is used as an interface tool between analysis software and the programming language. In the proposed algorithm, magnetic c...
