Optimisation of Large Wave Farms using a Multi-strategy Evolutionary Framework

no code implementations21 Mar 2020 Mehdi Neshat, Bradley Alexander, Nataliia Y. Sergiienko, Markus Wagner

The primary goal of this research is to maximise the total harnessed power of a large wave farm consisting of fully-submerged three-tether wave energy converters (WECs).

Evolutionary Image Transition and Painting Using Random Walks

no code implementations2 Mar 2020 Aneta Neumann, Bradley Alexander, Frank Neumann

We introduce an evolutionary image painting approach whose underlying biased random walk can be controlled by a parameter influencing the bias of the random walk and thereby creating different artistic painting effects.

Design optimisation of a multi-mode wave energy converter

no code implementations24 Jan 2020 Nataliia Y. Sergiienko, Mehdi Neshat, Leandro S. P. da Silva, Bradley Alexander, Markus Wagner

A wave energy converter (WEC) similar to the CETO system developed by Carnegie Clean Energy is considered for design optimisation.

A Hybrid Cooperative Co-evolution Algorithm Framework for Optimising Power Take Off and Placements of Wave Energy Converters

no code implementations3 Oct 2019 Mehdi Neshat, Bradley Alexander, Markus Wagner

Such arrays can be optimised for total energy output by adjusting both the relative positions of buoys in farms and also the power-take-off (PTO) parameters for each buoy.

A new insight into the Position Optimization of Wave Energy Converters by a Hybrid Local Search

no code implementations21 Apr 2019 Mehdi Neshat, Bradley Alexander, Nataliia Sergiienko, Markus Wagner

We compare the proposed hybrid method with other state-of-the-art search methods in five different wave scenarios -- one simplified irregular wave model and four real wave climates.

A Hybrid Evolutionary Algorithm Framework for Optimising Power Take Off and Placements of Wave Energy Converters

no code implementations15 Apr 2019 Mehdi Neshat, Bradley Alexander, Nataliia Sergiienko, Markus Wagner

In this research, we investigate the problem of maximising the energy delivered by farms of wave energy converters (WEC's).

A Cell-Division Search Technique for Inversion with Application to Picture-Discovery and Magnetotellurics

no code implementations21 Apr 2018 Bradley Alexander, Yang Heng Lee

In this work we improve upon previous work by defining a compact and expressive representation and search process able to describe and discover two and three dimensional spatial models.

Evolution of Images with Diversity and Constraints Using a Generator Network

no code implementations15 Feb 2018 Aneta Neumann, Christo Pyromallis, Bradley Alexander

To date this work has focused on the generation of images concordant with one or more classes and transfer of artistic styles.
