Web$\begingroup$ What's amusing about this solution is that it very likely uses an external method in RDKit which will probably then call back into a graph-theory library. Interesting the way the library calls chain. $\endgroup$ WebMar 24, 2024 · In plane geometry, a chord is the line segment joining two points on a curve. The term is often used to describe a line segment whose ends lie on a circle. The term is also used in graph theory, where a cycle …
WebIn graph theory, a dotted line represents the branch of a co-tree, which is known as a link or chord. Incidence matrix Analytically, in graph theory, an oriented graph can be represented by naming all branches and nodes and specifying how the branches are connected to each node. In the mathematical area of graph theory, a chordal graph is one in which all cycles of four or more vertices have a chord, which is an edge that is not part of the cycle but connects two vertices of the cycle. Equivalently, every induced cycle in the graph should have exactly three vertices. The chordal graphs may also … See more A perfect elimination ordering in a graph is an ordering of the vertices of the graph such that, for each vertex v, v and the neighbors of v that occur after v in the order form a clique. A graph is chordal if and only if it … See more In any graph, a vertex separator is a set of vertices the removal of which leaves the remaining graph disconnected; a separator is minimal if it has no proper subset that is also a separator. According to a theorem of Dirac (1961), chordal graphs are graphs … See more Subclasses Interval graphs are the intersection graphs of subtrees of path graphs, a special case of trees. Therefore, they are a subfamily of chordal graphs.

From a collection of … See more If G is an arbitrary graph, a chordal completion of G (or minimum fill-in) is a chordal graph that contains G as a subgraph. The parameterized version of minimum fill-in is fixed parameter tractable, and moreover, is solvable in parameterized … See more
