- A genetic algorithm has individuals coded as binary strings of length 27. Mutation is applied with a bit-wise probability of 1/27. What is the probability that the gene 17 is changed by mutation?
- 1/27
- 26/27
- 1/17
- It is not possible to say without knowing what happens to the other genes
- A number of on/off switches control a nuclear power plant, and a given configuration can be thought of as a state. It is desired to search the space of possible states to find one that minimises temperature fluctuations within the plant. It is decided to do this with a Genetic algorithm.
What representation do you think would be most suitable for this problem if there are n switches?
- A string of n binary values.
- A vector of n floating point numbers.
- A string of values each coming from the set {1,…,n}
- A tree with n terminal nodes (leaves).
- For which of the following types of problem representation would it not be suitable to use 2-point crossover?
- A permutation representing the order in which a series of operations are performed in an operating theatre.
- A binary string.
- A sequence of integers representing moves from the set {left, right, ahead}.
- A vector of floating-point numbers representing angles within a design problem.
- Which of the following offspring can not be created by one point crossover from two parents 000000 and 111111 ?
- 111111.
- 000000
- 111000
- 110011
- 011110
- 001111
- A mountain bike designer is trying to create a frame with certain desirable characteristics under simulation. To do this they must specify a set of n tube lengths and m angles between them. What representation do you think would be most suitable for this problem?
- A string of (n+m) binary values.
- A string of n values each between 1 and m.
- A vector of (n+m) floating point numbers.
- A permutation of the numbers 1 through to (n+m)
- A tree with (n+m) terminal nodes (leaves).
- It is necessary to schedule a set of appointments with a doctor so as to minimise the average waiting time per patient. There are n patients. What representation do you think would be most suitable for this problem?
- A string of n binary values.
- A vector of n floating point numbers.
- A string of values, each coming from the set 1 to n.
- A permutation of the numbers 1 to n.
- A tree with n terminal nodes (leaves).
