In this work, we investigate the ability of a Chunking GA (ChGA) to reduce the size of variable length chromosomes and control bloat. The ChGA consists of a standard genetic algorithm augmented by a communal building block memory system and associated memory chromosomes and operators. A new mxn MaxSum fitness function used for this work is also described. Results show that a ChGA equipped with ...

We introduce the notion of a matron M = ⊕Mn,m whose submodules ⊕Mn,1 and ⊕M1,m are non-Σ operads. We construct a functor from PROP to matrons and its inverse, the universal enveloping functor. We define the free matron H∞, generated by a singleton in each bidegree (m, n) 6= (1, 1), and define an A∞-bialgebra as an algebra over H∞. We realize H∞ as the cellular chains of polytopes KKn,m, among w...

In this study, the modified rice bran was tested to remove Pb(II) from water. Batch experiments were carried out to evaluate the adsorption characteristics of the modified rice bran for Pb(II) removal from aqueous solutions. The adsorption isotherms, thermodynamic parameters, kinetics, pH effect, and desorbability were examined. The results show that the maximum adsorption capacity of the modif...

Chaff cloud is widely used in target covering. In this paper, a jamming performance estimation strategy presented for the elliptical and cubic chaff clouds. The range profiles of composite models plane with are experimentally accessed an anechoic chamber using stepped-frequency waveform measurement system. Then, dimensions, characteristic length, distributing entropy equivalent scattering cente...

Abstract Waterhemp ( Amaranthus tuberculatus [Moq.] Sauer) escapes are common in midwestern U.S. soybean [ Glycine max (L.) Merr.] fields due to the continued rise herbicide-resistant (HR) populations. In a conventional harvesting system, weed seeds harvested with crop grain and spread back on field. Harvest seed control methods such as chaff lining concentrate seed-bearing into narrow row (cha...

The objective of this study has been to evaluate the stability of alpha-, (gamma+beta)-, and delta-tocopherols in rice bran oil chemically refined submitted to heating in a heater without air circulation and shielded from light, at temperatures of 100 degrees C and 180 degrees C. The collection of samples took place after 48, 96, 144, 192, 240, 336, and 432 h of heating and were stored in amber...

Classical conditioning is at the heart of most learning phenomena. It is thus essential that we develop accurate models of conditioning; since, psychological models rely heavily in verbal accounts that are necessarily imprecise it has become apparent that the development of computational models is imperious. However, we need to separate the wheat from the chaff. In this paper we review the main...

We demonstrate a SIMD C++ genetic programming system on a single 128 node parallel nVidia GeForce 8800 GTX GPU under RapidMind’s GPGPU Linux software by predicting ten year+ outcome of breast cancer from a dataset containing a million inputs. NCBI GEOGSE3494 contains hundreds of Affymetrix HG-U133A and HG-U133B GeneChip biopsies. Multiple GP runs each with a population of 5 million programs win...
