Dijkstra's algorithm updates distances by iteratively selecting the unvisited node with the smallest known distance, marking it as visited, and relaxing its outgoing edges. Relaxation involves checking if the path to a neighbor through the current node is shorter than the previously known path.
Conditions: Requires a priority queue or list to track unvisited nodes and their current shortest distances.; The graph must have non-negative edge weights (positive in the pseudocode).
