Solution

The correct answer is Radial

Key Points

• Radial: ❌ "Radial" is not a parent selection technique used in genetic algorithms. It is not related to the process of selecting individuals for reproduction in evolutionary computation.
• Tournament: ✅ Tournament selection is a widely-used parent selection technique where a subset of individuals is randomly chosen, and the best individual from this subset is selected as a parent.
• Boltzmann: ✅ Boltzmann selection uses a probabilistic approach based on simulated annealing to select parents, where selection pressure depends on a temperature parameter that changes over time.
• Rank: ✅ Rank selection sorts individuals by fitness and assigns probabilities to them based on their rank, ensuring a diverse selection of parents.

Additional Information

• Parent Selection Techniques: In genetic algorithms, parent selection is crucial for choosing individuals to reproduce and create offspring. Common techniques include Roulette Wheel Selection, Tournament Selection, Rank Selection, and Boltzmann Selection.
• Radial: This term is not associated with genetic algorithms or parent selection techniques, making it the correct answer for "not a parent selection technique."

Hence, the correct answer is: option 1) Radial
