Show hintHide hint
Look at the bottom layer of the Hasse diagram.
3Question 3.
What defines a cover relationship in a poset?
- A direct relationship with intermediates
- A direct relationship without intermediates
- A relationship with equal elements
Show hintHide hint
Think about direct pathways in a Hasse diagram.
4Question 4.
True or False: Every poset has a greatest element.
- True
- False
Show hintHide hint
Consider posets with incomparable elements.
Question 5.
Given a set of tasks A, B, C, and D with dependencies (A -> B, A -> C, B -> D), create a proper Hasse diagram and perform a topological sort.
Show hintHide hint
Once you visualize it, look for minimal elements for sorting.
Question 6.
Illustrate a scenario where there are three tasks that can be done in any order but depend on a fourth completion. How would that look in both a Hasse diagram and via topological sorting?
Show hintHide hint
Draw connections and analyze the flow of dependencies.
