Topics include evolutionary operators (mutation/crossover/recombination), properties preserved in permutation-based genotypes, parent selection with fitness proportional selection, and fitness sharing effects using gene-position similarity. It also tests diversity mechanisms, multiobjective versus single-objective differences, Pareto optimality, and reinforcement learning updates via Q-learning and SARSA.","i IN4050-Introduction to Artificial Intelligence and Machine Learning  \nSpring 2025  \nMay 27  \n03:00 PM-07:00 PM(4 hours)  \nAll questions should be answered!  \nEach question is assigned a weight which is indicated.The maximum number of points for the whole set is 100 points.The course teachers will visit the exam room once around the middle of the exam time.  \nMultiple Choice questions make up 70%of the points on the exam.For these,exactly one alternative is correct,unlessotherwise specified.  \nPermitted materials:NoneAn on-screen calculator is available.  \nYou may answer in English,Norwegian,Danish or Swedish.  \n# 1 In Search/Optimization,what is true about exploration?Select one alternative:\n\nOExploration is only used for continuous optimization  \nOHillclimbing is a purely exploratory technique  \nOExhaustive search is a purely exploratory technique  \nO Gradient Descent does more exploration than exploitation  \nMaximum marks:2  \n# 2 Which is true about optimization algorithms?Select one alternative:\n\nO Simulated annealing balances exploitation and exploration with the temperature parameter  \nO Simulated annealing only selects neighbor solutions that are better than the current solution  \nOHillclimbing has more randomness than simulated annealing  \nO Gradient descent can be used for discrete optimization  \n# 3 Which is typically not a part of an evolutionary algorithm(EA)?Select one alternative:\n\nOA termination criterion  \nOA temperature control  \nOA fitness function  \nOA population  \nMaximum marks:2  \n# 4 Which is not a variation operator in Evolutionary Algorithms?Select one alternative:\n\nO Fitness Sharing  \nO Recombination  \n○ Crossover  \nO Mutation  \nMaximum marks:2  \n# 5 What property of the elements of a solution

population,and you are about to doparent selection from it.You will calculate the selection probability of each individual.Note that the probability you calculate isfor a single selection,not the probability that the individual gets selected into the pool of parents after N different selections.What is the selection probability of each individual given Fitness Proportional selection?Select one alternative:  \nO Individual 1:1/3.Individual 2:1/3.Individual 3:1/3  \nO Individual 1:0.Individual 2:0.Individual 3:1  \nO Individual 1:1/6.Individual 2:2/6.Individual 3:3/6  \nOd)Individual

selections,with the same individuals as in the previous question.Howwould that affect their fitness scores?Assume the similarity measure between individuals is based on how many genes are inthe same location in their genotype.How would the probability of selecting each individual change?Select one alternative:  \nO Individual 3 would become more likely to be selected,the other two less likely to be selected  \nO Individual 1 would become more likely to be selected,the other two lesslikely to be selected  \nOIndividual 2 and 3 would become more likely to be selected,individual 1 less likely to be selected  \nO Individual 2 would become more likely to be selected,the other two less likely to be selected  \n# 8 Which is not a method to encourage diversity in evolutionary algorithms?Select one alternative:\n\nO Fitness Sharing  \nO Elitism  \nO Crowding  \nO Speciation  \n# 9 Which two differ most between multiobjective and single-objective evolutionary algorithms?Select exactly two
