Define what a cover is in the context of posets.
Think about elements immediately above others in a diagram.
What is a maximal element?
Consider elements without anything on top in a Hasse diagram.
What defines a cover in a poset?
Refer to the definitions we've just discussed.
True or False: A poset can have more than one minimal element.
Consider how many elements can have no dependency below them.
Design a Hasse diagram for a given set E = {a, b, c} with relations a < b, a < c, and b < c. Identify the covers, maximal, and minimal elements.
Focus on the relationship levels.
Given a set of tasks with dependencies described, explain how a circular dependency impacts the topological sort and provide a solution.
What happens if tasks rely on one another in a loop?
