Optimisation of the gas-exchange system of combustion engines by Genetic Algorithm

C. D. Rose, S. R. Marsland, D. Law
2000 2009 4th International Conference on Autonomous Robots and Agents  
This paper proposes a new method for the optimisation of these systems through the use of modified Genetic Algorithm techniques, principally a variable length chromosome encoding.  ...  Current techniques for the optimisation of combustion engine gas-exchange systems still predominantly use trial and error.  ...  While single rpm optimisations may have some application in areas such as stationary power generation, for the majority of potential applications, a solution which only gives good performance at a single  ...

Genetic Algorithms Optimised Chemical Reactors Network Application: Hydrogen Emissions Performance of a V2527 engine

C. Leong, S. Blakey
2015 USES Conference Proceedings   unpublished
A technique, namely Genetic Algorithms optimised Chemical Reactors Network (GACRN) was implemented to search for the flow splits of a V2527 engine combustor.  ...  Emissions from hydrogen combustion in aircraft engines are one of the concerns of this future alternative fuel. Full scale engine tests are costly.  ...  Data on V2527 engine performance was provided by Fredrick Svensson, formally of FOI, the Swedish Defence Research Agency. This paper is also dedicated to the memory of Prof.  ...

Configuration of a genetic algorithm for multi-objective optimisation of solar gain to buildings

Ralph Evins, Philip Pointer, Ravi Vaidyanathan
2010 Proceedings of the 12th annual conference on Genetic and evolutionary computation - GECCO '10  
We report the formulation and implementation of a genetic algorithm to address multi-objective optimisation of solar gain to buildings with the goal of minimising energy consumption and hence limiting  ...  Heuristic optimisation approaches hold significant promise to balance complex tradeoffs in building design; however the unique nature of each building optimization problem limits broader implementation  ...  Low values for P m are more harmful than low values for P c . The values of P m = 0.2 and P c = 0.5 have been chosen for subsequent optimisations.  ...

Comparing genetic algorithms and particle swarm optimisation for an inverse problem exercise

C. R. Mouser, S. A. Dunn
2005 ANZIAM Journal  
This work describes how a genetic algorithm optimises the properties of a genetic algorithm and a particle swarm optimisation in order to produce algorithms  ...  We describe the performance of two population based search algorithms (genetic algorithms and particle swarm optimisation) when applied to the optimisation of a structural dynamics model.  ...  The difficulty with the application of the optimisation algorithms is that they need to be tuned.  ...

GI4GI

Mark Harman, Justyna Petke
2015 Proceedings of the Companion Publication of the 2015 on Genetic and Evolutionary Computation Conference - GECCO Companion '15  
Genetic improvement (GI) has been successfully used to optimise non-functional properties of software, such as execution time, by automatically manipulating program's source code.  ...  Therefore, we propose the GI4GI framework (and two illustrative applications).  ...  In this way we use genetic improvement to find a fitness function to guide a subsequent genetic improvement that finds an energy efficient version of the given program or application.  ...

2013 Latin American Journal of Solids and Structures  
Optimisation of stacking sequence for composite panels under slamming impact loads using a genetic algorithm method is studied in this paper.  ...  Results obtained from these analyses reveal the fact that the adopted approach based on a genetic algorithm is highly capable of performing such optimisations.  ...  The parameter C has a constant value throughout any time using of the optimisation process. In other words, the value of parameter C is unchanged for all chromosomes in all generations.  ...
