undirected edge उदाहरण वाक्य

उदाहरण वाक्य

1. Fraenkel, Scheinerman, and Ullman show that "'Undirected Vertex Geography "'can be solved in polynomial time, whereas "'Undirected Edge Geography "'is PSPACE-complete, even for planar graphs with maximum degree 3.
2. The former type of graph is called an " undirected graph " and the edges are called " undirected edges " while the latter type of graph is called a " directed graph " and the edges are called " directed edges ".
3. A valid schedule for the disjunctive graph may be obtained by finding an acyclic orientation of the undirected edges  that is, deciding for each pair of non-simultaneous tasks which is to be first, without introducing any circular dependencies  and then ordering the resulting directed acyclic graph.
4. For instance, a Bayesian network represents a system of probabilistic events as vertices in a directed acyclic graph, in which the likelihood of an event may be calculated from the likelihoods of its predecessors in the DAG . In this context, the moral graph of a DAG is the undirected graph created by adding an ( undirected ) edge between all parents of the same vertex ( sometimes called " marrying " ), and then replacing all directed edges by undirected edges.
5. For the special case of conjunctive queries in which all relations used are binary, this notion corresponds to the treewidth of the dependency graph of the variables in the query ( i . e ., the graph having the variables of the query as nodes and an undirected edge \ { x, y \ } between two variables if and only if there is an atomic formula R ( x, y ) or R ( y, x ) in the query ) and the conjunctive query is acyclic if and only if its dependency graph is acyclic.
