Practical Application of Genetic Algorithm

Question

I am doing a project work on non dominated sorting or multivector sorting algorithm, which is used in selection part of a genetic algorithm. I have searched on web but still I dont know about practical applications of Genetic Algorithm. I only know that it is used in Testing, but I dont know how it works there. Can you suggest some practical applications of Genetic Algorithms?

Answer 1

Genetic algorithms are great for feature selection used by machine learning algorithms.

Many times, there are just too many features in the data set, which makes it too noisy, so we sometimes handle this by reducing the dimensionality of the problem, by selecting only a subset of the features. For this purposes - Genetic Algorithms seems to work great in many cases (Empirically), and its usage is wide both in research and in real world applications that have very high dimensionality.

For example: text analyzis, with the bag of words model: Sometimes we want to use only a subset of the words, and not all of them, so we use a feature selection algorithm for it, and GA is one of them.
