Question 1.
Define a spanning tree.
Show hintHide hint
Think about what makes a tree in graph theory.
Question 2.
What does the term 'acyclic' mean?
Show hintHide hint
Consider the meaning of the prefix 'a-' added to 'cyclic'.
3Question 3.
What is the goal of Prim's Algorithm?
- To find the shortest path
- To find a minimum cost spanning tree
- To find all cycles in a graph
Show hintHide hint
Reflect on the definition of a spanning tree.
4Question 4.
True or False: A spanning tree can have cycles.
- True
- False
Show hintHide hint
Remember the acyclic property of trees.
Question 5.
Consider the following graph with vertices A, B, C, D, and edges connecting them with weights. Apply Prim's Algorithm to find the Minimum Cost Spanning Tree and illustrate the choices made at each step.
Show hintHide hint
Keep track of the already connected vertices to avoid cycles.
Question 6.
If you have a densely connected graph where many edges have the same minimum weight, how does this affect Prim's Algorithm?
Show hintHide hint
Consider how the algorithm's flexibility can still maintain the properties of a minimum spanning tree.
