Consider a navigation system where UCS is used to find the shortest path between two locations. The graph representing the road network has varying edge costs corresponding to the distance between intersections. What advantage does UCS offer in this scenario compared to other search algorithms?

a: UCS guarantees finding the shortest path regardless of edge costs. Explanation

Explanation

b: UCS efficiently explores paths based on their cumulative costs, ensuring the shortest path is found first. Explanation

Explanation

c: UCS always selects the path with the lowest number of steps, leading to shorter travel times. Explanation

Explanation

d: UCS prioritizes paths with the lowest heuristic values, resulting in faster navigation. Explanation

Explanation

Which of the following is true about uniform cost search?

a: It is always complete. Explanation

Explanation

b: It is always optimal. Explanation

Explanation

c: It is never complete nor optimal. Explanation

Explanation

d: If the step costs are positive, it is complete and optimal. Explanation

Explanation

When is uniform cost search inefficient?

a: When the edge costs are not all the same Explanation

Explanation

b: When the edge costs are all the same Explanation

Explanation

c: When the cost of the optimal solution is low Explanation

Explanation

d: When the cost of the optimal solution is high Explanation
