Question
Which of these is NOT a specified method that is used for the selection of the parents?
A. Steady-state
B. Tournament Selection
C. Boltzmann selection
D. Elitism
Answer
A. Steady-state
Explanation
In the context of genetic algorithms, several methods are commonly used for selecting parents to produce the next generation. These include:
- Tournament Selection: This method involves selecting a subset of individuals from the population and choosing the best among them based on fitness to become parents.
- Boltzmann Selection: This approach uses a temperature parameter to control selection pressure, allowing for adaptive selection that can change as the algorithm progresses.
- Elitism: This method ensures that the best individuals from the current generation are carried over to the next without any changes, preserving their genetic material.
Steady-State Selection, while mentioned in some contexts related to genetic algorithms, is not typically specified as a method for selecting parents. Instead, it refers to a strategy where only a few individuals are replaced in each generation, maintaining most of the population6. Therefore, Steady-State is not a standard parent selection method like the others listed.
The correct answer to which of these is NOT a specified method used for the selection of parents is A. Steady-state.
