This paper presents a genetic algorithm that evolves a fourpart musical composition–melodically, harmonically, and rhythmically. Unlike similar attempts in the literature, our composition evolves from a single musical chord without human intervention or initial musical material. The mutation rules and fitness evaluation are based on common rules from music theory. The genetic operators and indi...

Abstract—There are many reasons to be concerned about the use of non-native species or non-local genetic material in restoration efforts. An overview of these issues is presented. It is argued that site restoration is more than just successful vascular plant establishment, and that local plant material should be used whenever possible. However, it is recognized that time and money often constra...

We use a mitochondrial DNA (mtDNA) dataset provided by the FBI to build classifiers that can guess the ethnicity of the bearer of an mtDNA sample, using a number of different algorithms. Mitochondrial DNA is the genetic material that is found in mitochondria, organelles that reside inside the cells. The DNA found in mitochondria is relatively small in size but is highly informative and is there...

Changes in seed dormancy were selected during the domestication of crop plants from wild-plant species, because some features of dormancy that provide ecological advantages presented agronomic disadvantages within a farmed system. Seed dormancy varies widely among seed batches, even for seeds of the same genotype, indicating large environmental influences. For genetic studies, it is essential t...

Wheat (Triticum aestivum L.) is known to be the world-leading cereal grain and the most important food in the world of agriculture.  Wheat offers a great wealth of material for genetic studies due to its wide ecological distribution and host of variation for various morphological and physiological characters.  To evaluate the genetic control of physical traits of grain in two crosses of winter ...

Traditionally, the objective of a service facility layout problem is to minimize the material handling cost and optimize the physical spaces that support a productive activity of the service system. Service delivering interface has direct impact to the efficiency and effectiveness of service system in light of customer’s contact. Layout problem of service facilities has received little attentio...

According to [1], the material handling cost comprises about 20-50% of the total operating cost of the facility layout. Typical research on facility layout concentrate on static layout problems where from-to charts are used to evaluate the layout. These layouts are not flexible enough to accommodate any future changes in production. Research on dynamic facility layout also has used the concept ...

tall wheat grass (agropyron elongatum), as many other grasses, benefits from wide genetic bases in iran. estimation of genetic diversity and a selection of suitable genotypes is the initial step for developing adaptable synthetic varieties in many cool season grasses. in order to investigate production, variation and genetic similarity of 25 tall wheat grass genotypes, an experiment was conduct...

Genetic marker data are likely to be obtained from a relatively small proportion of the individuals in many livestock populations. Information from genetic markers can be extrapolated to related individuals without marker data by computing genotype probabilities using an algorithm referred to as peeling. However, genetic markers may have many alleles and the number of computations in traditiona...
