Q

For defining a search problem, we need

1 - A state description and a goal description
2 - A state function and a goal function
3 - A state function and a goal description
4 - A state description and a goal function

A

4

80
Q

True or False: A state description is an abstract representation of the current state of a puzzle. The set of all such descriptions is called the state space.

A

True

81
Q

Which statements about ”Local Search” are true?

1 - The Approach is to keep a single ”current” state (or a fixed number of them) and to try to improve it by maximizing a heuristic evaluation.
2 - It uses a lot of memory.
3 - It needs much time to find solutions in large or infinite state spaces.
4 - It guarantees completeness (that a solution is always found) and optimality (that the best/shortest solution is found).
5 - They often quickly finds solutions in large or infinite state spaces.
6 - There are no guarantees for completeness (that a solution is always found) or optimality (that the best/shortest solution is found).

A

1, 5 and 6 are correct

82
Q

True or False: Choosing a good state representation may already be crucial for finding a good solution.

A

True

83
Q

Which statements about ”Heuristic” are true?

1 - In search algorithms, a heuristic always denotes a function that compute the quality of a given state.
2 - It denotes a rule and it should to be note that heuristics may never go wrong!
3 - In search algorithms, a heuristic often denotes a function that estimates the quality of a given state.
4 - The word is derived from the russian word ”heurestika” and translates as ”always valid”.
5 - The word is derived from the greek word ”heurisko” and translates as ”I find”.
6 - It informally denotes a ”rule of thumb“ and it should to be note that heuristics may also go wrong!

A

3, 5 and 6 are correct

84
Q

True or False: The Algorithm from the Beam Search is…

  • Start with randomly generated states.
  • At each iteration, all the successors of the current state are generated.
  • Select the k best successors from the complete list and repeat.
A

True

85
Q

Match the statements to the correct area of Hill-climbing- search

  1. States may be refined in multiple ways; → similarity along various dimensions
  2. select the successor node ramdomly; better nodes have a higher probability of being selected
  3. Different initial positions result in different local optima; → make several iterations with different starting positions
  4. location: states; elevation: heuristic value (objective function); Assumption: states have some sort of (linear) order; continuity regarding small state changes

a. State Space Landscape
b. Stochastic Hill-Climbing
c. Random Restart Hill-Climbing
d. Multi-Dimensional State-Landscape

Q

If the algorithm will stop as soon as is at the top of a hill, this will e named ”Local Optima” and
is a main problem. Of which Search variant?

1 Simulated Annealing Search
2 Beam Search
3 Every of the three named Search variants.
4 Hill-Climbing Search

A

4

87
Q

True or False: Information from different beams is combined so the Beam search is different from k parallel hill-climbing searches, but the effectiveness suffers from lack of diversity of the k states.

A

True

88
Q

Simulated Annealing Search is …

1 . . . modelled after mutation of DNA and comperable to a stochastic hill-climbing step.
2 . . . a combination of hill-climbing and random walk.
3 . . . only used to find the right temperature in metallurgy.
4 . . . the same idea as in Stochastic Beam Search but uses ”sexual” reproduction.

Q

True or False: In the Genetic Algorithms there will be the next generation produced by selection, cross-over, and mutation.

True

Q

True or False: The Genetic Programming is popularized by David Fogel.

True

    • Solve each of these simpler problems by possibly solving them again by division

    • Combine the partial solutions to a …

Q

What can happen, if the analysis of the solutions of a recursive solution rise to a simple non-recursive solution?

1 - Much less memory is needed and the length of the solution is greatly reduced.
2 - Much less memory is needed, but the solution length cannot be reduced.
3 - Nothing changes.
4 - The same memory is needed, but the length of the solution is reduced.

Q

Which of the following techniques have we considered to be particularly useful for different steps when solving a Sudoku puzzle?

  1. check which values can be filled in a selected square
  2. use the value that has been filled in for reducing the set of possible values in neighboring squares
  3. selecting the next square that could be filled in
  4. try out one of several possible values and possibly come back later if it doesn’t work out

a. heuristics
b. backtracking search
c. constraint propagation
d. constraint satisfaction
