Constrained optimization of the shape of a wave energy collector by genetic algorithm

McCabe, A.P. - In: Renewable Energy 51 (2013) C, pp. 274-284

Wave energy extraction requires the conversion of the energy within the waves to drive the power take off system, often by means of a principal interface, or collector. This paper describes part of the development of a robust, systematic method of optimizing the collector shape to improve energy...
