It is indeed that there is a large class of interesting problems for which no reasonably fast algorithms have been developed. Many of these problems are optimization problems that arise frequently in many practical applications. For the last few decades genetic algorithm has been playing a significant role in optimization problems. It is being used in structural optimization, functional optimization, database query optimization, parametric optimization and so on. The MMKP (Multi-dimensional Multiple Choice Knapsack Problem), a complex variant of 0-1 Classical Knapsack Problem, is an...

Iris recognition has received increasing attention recently in the world. A biometric system provides automatic identification of an individual based on a unique feature or characteristic possessed by the individual. Iris recognition is regarded as themost reliable and accurate biometric identification system available. Most commercialiris recognition systems use patented algorithms developed by Daugman, and these algorithms are able to produce perfect recognition rates. However, published results have usually been produced under favorable conditions, and there have been no independent trials...
