What is uniform-cost search and how does it work?

Understand the Problem

The question is about understanding the uniform-cost search algorithm, particularly its steps and how it functions when step costs are unequal compared to breadth-first search (BFS) when path costs are equal.

Answer

Uniform-Cost Search expands the node with the lowest path cost to find the least cost path.

Uniform-Cost Search is a search algorithm used to explore nodes based on the lowest path cost. It expands the node with the smallest cumulative cost from the start node and continues until the goal node is reached. This algorithm is used when path costs vary.

Answer for screen readers

Uniform-Cost Search is a search algorithm used to explore nodes based on the lowest path cost. It expands the node with the smallest cumulative cost from the start node and continues until the goal node is reached. This algorithm is used when path costs vary.

More Information

Uniform-Cost Search is particularly effective in graphs with differing edge costs, ensuring the least cost path is identified for optimal performance.

Tips

A common mistake is confusing UCS with other search algorithms like BFS, which do not account for path cost.
