Question: In the context of Dijkstra\'s algorithm, what does \'relaxation\' refer to?

Options:

Correct Answer: Updating the distance of a node

Solution:

Relaxation refers to the process of updating the shortest known distance to a node if a shorter path is found.

In the context of Dijkstra's algorithm, what does 'relaxation' refer to?

Step 1: Understand that Dijkstra's algorithm is used to find the shortest path in a graph.
Step 2: Know that each node (or point) in the graph has a distance value that represents the shortest known distance from the starting point.
Step 3: When exploring a node, check all its neighboring nodes to see if there is a shorter path to them through the current node.
Step 4: If a shorter path is found to a neighboring node, update that node's distance value to this new shorter distance.
Step 5: This process of checking and updating distances is called 'relaxation'.
