Thread: Partial Orders : Hasse Diagrams

For A  {a, b, c, d, e}, the Hasse diagram for the poset
(A, R) is shown in Fig. 7.23.
(a) Determine the relation matrix for R.
(b) Construct the directed graph G (on A) that is associated with R.
(c) Topologically sort the poset (A,R ).

If you want a feedback on your work, you should show it. You can use the [code]...[/code] tags to write the matrix because alignment is preserves between those tags.
