Final answer:
Dijkstra's algorithm is a graph search algorithm that finds the shortest path between nodes in a weighted graph by assigning a weight to each segment or edge in the graph.
Step-by-step explanation:
Dijkstra's algorithm is a graph search algorithm that finds the shortest path between nodes in a weighted graph. It assigns a number or weight to each segment or edge in the graph to determine the shortest path. The algorithm starts at a specific node and iteratively explores the adjacent nodes to find the shortest path to each node.
