Q4. In the context of genetic algorithms and their selection processes, why might the Roulette Wheel Selection method be considered advantageous yet potentially problematic?
a. It guarantees the selection of the best individual in every generation, ensuring rapid convergence.
b. It distributes selection probabilities based on fitness, favouring fitter individuals but potentially sidelining lesser-fit individuals over time.
c. It always promotes diversity by selecting individuals randomly, ensuring a wide range of solutions in subsequent generations.
d. It eliminates the need for a fitness function, relying solely on random chance for selection

Answer:- 

Q5. Which type of generation gap typically leads to higher selection pressure?
a. No gap
b. Small gap
c. Large gap
d. The type of gap doesn’t affect selection pressure
