Genetic parameters for eggshell traits in ostriches
British Poultry Science, 20121. A study was conducted on ~14000 ostrich eggs to estimate genetic parameters for eggshell traits that could benefit the hatchability of ostrich eggs. Traits measured included the number of pores on the eggshell, the average diameter of these pores, the total area of pores on the eggshell, permeability (pore area/shell thickness) and eggshell ...

Three interconnected parameters for genetic algorithms
Proceedings of the 11th Annual conference on Genetic and evolutionary computation, 2009When an optimization problem is encoded using genetic algorithms, one must address issues of population size, crossover and mutation operators and probabilities, stopping criteria, selection operator and pressure, and fitness function to be used in order to solve the problem.

Genetic parameters and genetic trends for reproductive traits in Egyptian buffalo
Animal Reproduction Science, 2021Reproductive traits are important for farm profitability because failure to reproduce is the primary reason for culling animals. Study objectives were to estimate genetic parameters and evaluate the trends for reproductive traits. Age at first calving (AFC), gestation length (GL), postpartum interval to pregnancy (PPIP), calving interval (CI) and ...

Band-structure parameters by genetic algorithm
Physical Review B, 1996A genetic algorithm has been used to solve a complex multidimensional parameter-fitting problem. We will focus on the parameters of an empirical tight-binding Hamiltonian. The method is used to approximate the electronic energy band structure if energy values are known for a few wave vectors of high symmetry. Compared to the usual manual procedure this

Genetic Parameters for Testes Traits in Swine
Journal of Animal Science, 1984Data were collected from 1,245 Duroc boars and 527 Yorkshire boars. This represents 128 Duroc and 57 Yorkshire sires. Body weights, testis length and combined testes width at 140 and 168 d were obtained. Of these boars, 432 were castrated at a later age to evaluate relationships between in situ measures and excised testis traits.

Impact on Genetic Algorithm of Different Parameters
2008Genetic algorithm is a highly efficient parallel evolution algorithm of the global search which is decided by the balance of the exploitation and exploration. This balance also depends on population size, the biggest evolution of algebra, coding length, crossover rate and mutation rate, etc., therefore, the set of evolution parameters for the search ...

Genetic parameters of growth curve parameters in male and female chickens
British Poultry Science, 19991. Individual growth curves of 7143 chickens selected for the form of the growth curve were fitted using the Laird form of the Gompertz function, BW4=BW0xe(L/K)(1-e-Kt) where BWt is the body weight at age t, BW0 the estimated hatching weight, L the initial specific growth rate and K the maturation rate. 2. Line and sex effects were significant for each
