A Faster Algorithm For Calculating Hypervolume, Lyndon While, Philip Hingston, Luigi Barone, Simon Huband Jan 2006

A Faster Algorithm For Calculating Hypervolume, Lyndon While, Philip Hingston, Luigi Barone, Simon Huband

Research outputs pre 2011

We present an algorithm for calculating hypervolume exactly, the Hypervolume by Slicing Objectives (HSO) algorithm, that is faster than any that has previously been published. HSO processes objectives instead of points, an idea that has been considered before but that has never been properly evaluated in the literature. We show that both previously studied exact hypervolume algorithms are exponential in at least the number of objectives and that although HSO is also exponential in the number of objectives in the worst case, it runs in significantly less time, i.e., two to three orders of magnitude less for randomly generated and …

Fixture-Scheduling For The Australian Football League Using A Multi-Objective Evolutionary Algorithm, Luigi Barone, Lyndon While, Paul Hughes, Philip Hingston Jan 2006

Fixture-Scheduling For The Australian Football League Using A Multi-Objective Evolutionary Algorithm, Luigi Barone, Lyndon While, Paul Hughes, Philip Hingston

Research outputs pre 2011

AFL football is a team sport that entertains millions and contributes a huge amount of money to the Australian economy. Scheduling games in the AFL is difficult, as a number of different, often conflicting, factors must be considered. In this paper, we propose the use of a multi-objective evolutionary algorithm for determining such a schedule. We detail the technical details needed to apply a multi-objective evolutionary algorithm to this problem and report on experiments that show the effectiveness of this approach. Comparison with actual schedules used in the AFL demonstrates that this approach could make a useful contribution.

Opto-Vlsi-Based Correlator Architecture For Multiwavelength Optical Header Recognition, Muhsen Aljada, Kamal E. Alameh, Khalid Al-Begain Jan 2006

Opto-Vlsi-Based Correlator Architecture For Multiwavelength Optical Header Recognition, Muhsen Aljada, Kamal E. Alameh, Khalid Al-Begain

Research outputs pre 2011

A novel optical correlator employing an opto-very-large-scale-integration (VLSI) processor to construct the routing lookup table, in conjunction with an array of fiber Bragg gratings (FBGs) for multiwavelength optical header recognition is demonstrated. The FBG array provides wavelength-dependent time delays, whereas the opto-VLSI processor generates wavelength intensity profiles that match arbitrary bit patterns. The recognition of 4-b optical patterns is experimentally demonstrated at 2.2 Gb/s by showing that the correlator produces an autocorrelation waveform of high peak whenever the input bit pattern matches the wavelength intensity profile.

Dynamic Optical Comb Filter Using Opto-Vlsi Processing, Zhenglin Wang, Kamal Alameh, Rong Zheng, Chung Poh

Research outputs pre 2011

Reconfigurable multi-channel optical filters are presented in this paper. The operation principle of the reconfigurable filter is based on the dynamic beam steering capacity of Opto-VLSI processor in conjunction with a high dispersion free space grating. The dispersion grating separates the input signal spectrum while the Opto-VLSI processor is driven by optimised phase holograms to dynamically select the wavelengths to be coupled into the output port. Experimental results show that up to 8 bands can be synthesised, with a wavelength tuning span of 10 nm and a 3dB bandwidth less than 0.5nm.
