Arrange the following steps in proper sequence involved in a Genetic Algorithm:
(A) Selection
(B) Initialization
(C) Crossover
(D) Mutation
(E) Evaluation
Choose the correct answer from the options given below:
1.(A), (B), (C), (D), (E)
2.(E), (A), (B), (D), (C)
3.(B), (E), (A), (C), (D) ✓ Correct
4.(A), (C), (B), (D), (E)
Solution
The correct answer is (B), (E), (A), (C), (D).
Key Points
Initialization (B): This is the first step in a Genetic Algorithm where a population of potential solutions is generated. The initial population can be created randomly or based on some heuristic.
Evaluation (E): Each individual in the population is evaluated to determine its fitness. This fitness function is problem-specific and determines how well an individual solves the problem.
Selection (A): Based on the fitness scores, individuals are selected for reproduction. Individuals with higher fitness have a higher chance of being selected.
Crossover (C): In this step, pairs of individuals are combined to produce offspring. This is done to explore new regions of the solution space. Various methods like single-point crossover, multi-point crossover, or uniform crossover can be used.
Mutation (D): After crossover, the offspring may undergo mutation where some of their genes are altered. This is done to maintain genetic diversity within the population and to avoid local minima.
Thus the correct answer is (B), (E), (A), (C), (D).
Additional Information
The Genetic Algorithm is an optimization technique based on the principles of natural selection and genetics. It is used to find approximate solutions to complex problems where traditional methods may be infeasible.
Genetic Algorithms are widely used in various fields such as machine learning, artificial intelligence, and operations research to solve optimization and search problems.
