Semantically-based crossover in genetic programming : application to real-valued symbolic regression (Springer, 2011-06)We investigate the effects of semantically-based crossover operators in Genetic Programming, applied to real-valued symbolic regression problems. We propose two new relations derived from the semantic distance between ...

(ACM, 2011-07-12)This paper examines how the semantic locality of a search operator affects the fitness landscape of Genetic Programming (GP). We compare the fitness landscapes of GP search when standard subtree mutation and a recently ...

(The Journal of Solid Waste Technology and Management, 2010-03)Managing municipal and industrial biosolids by recycling through the land is currently a strategic policy direction in Ireland. Although recycling biosolids is a plausible management alternative it can also be a contentious ...

(Springer, 2011-08)This paper compares a 3-dimensional hydro-ecological model with a 2-dimensional model simulating the distribution and fate of Escherichia Coli (E.Coli) discharges from a sewage treatment plant discharging into Dublin Bay, ...

(Springer, 2011-04-27)This paper investigates the effects of early stopping as a method to counteract overfitting in evolutionary data modelling using Genetic Programming. Early stopping has been proposed as a method to avoid model overtraining, ...

(Springer, 2011-04-27)There have been many approaches to modularity in the field of evolutionary computation, each tailored to function with a particular representation. This research examines one approach to modularity and grammar modification ...

(Wiley, 2011-04-18)Hematite nanorod arrays were activated through proper control of annealing conditions. The 100-fold improvement in photocurrent was correlated with increased absorption and Sn doping from the tin oxide coated glass ...
-
(University College Dublin. Institute for British-Irish Studies, 2010)This largely historiographical paper examines the initial inclusion of native Gaelic clergy in the plantation church in Ulster and their gradual disappearance over the course the next twenty-five years. This was a highly ...

(Elsevier, 2011-04)This study investigated the glyphosate adsorption by water treatment residual (termed as alum sludge) in dewatered form (DAS) and liquid form (LAS). Batch adsorption tests were carried out with DAS at different pH, particle ...

(Taylor & Francis, 2010-07)The generation of alum sludge from drinking water purification process remains inevitable when aluminium sulphate is used as primary coagulant for raw water coagulation. Sustainable managing such the sludge becomes an ...
