Expert Solution
Step 1

The primary goal of the uniform-cost search is to find a path to the goal node which has the lowest cumulative cost. 

Uniform-cost search expands the node with least path cost.

In uniform-cost search, goal test on the node is performed when it is selected for expansion.

-----

Uniform cost search algorithm is a variant of Dijikstra's algorithm. In uniform cost search algorithm, instead of inserting all vertices into a priority queue, we insert only source, then one by one insert when needed.
