Prim's algorithm, also known as Jarník's algorithm, is a greedy algorithm used to find the minimum spanning tree (MST) of a weighted, undirected graph. A minimum spanning tree is a subset of the edges in a graph that connects all the vertices together with the minimum total weight of the edges, without forming a cycle. In simpler terms, it's like finding the cheapest way to connect all the cities in a network, with the condition that there are no unnecessary loops in the connections.

What is the primary advantage of using Prim's algorithm for network design?

Selecione uma das seguintes:

  • It guarantees the fastest possible connection between any two points in the network.

  • It allows for easy expansion and modification of the network without affecting its efficiency.

  • It ensures that the network is highly secure and resistant to disruptions.

  • It minimizes the total cost of connecting all points in the network.

How does Prim's algorithm ensure that there are no unnecessary loops in the connections?

Selecione uma das seguintes:

  • It starts with a single vertex and gradually adds edges, ensuring that each new edge connects a vertex already in the tree to a vertex not yet in the tree.

  • It uses a greedy approach, always selecting the edge with the minimum weight, which automatically avoids creating loops.

  • It calculates the total weight of all possible paths and selects the one with the minimum weight, eliminating any loops.

  • It uses a data structure called an adjacency list, which prevents the formation of cycles.
