WebThe process of constructing a compatible total order for a given partial order is called topological sorting. It is known that every finite partially ordered set (A, ≼) can be represented by a directed graph G. The vertices of G correspond to the elements of set A, and the edge from a to b exists if and only if a ≼ b. WebA topological graph is also called a drawing of a graph. An important special class of topological graphs is the class of geometric graphs, where the edges are represented by …
