Click the left arrow button in the slider. This decreases the degree of the polynomial to zero. A zero-degree polynomial fit is just a mean line. Figure 13.6: Fit Window with Mean Line Click twice on ...

Graph Polynomial: An algebraic expression that encodes key combinatorial properties of a graph. Tutte Polynomial: A two-variable polynomial invariant capturing a wide range of graph properties ...

Polynomial-time isomorphism tests are known for many natural classes of graphs including the class of planar graphs, 9 classes of graphs embeddable in a fixed surface 4, 16 and more generally classes ...

Many graph polynomials, such as the Tutte polynomial, the interlace polynomial and the matching polynomial, have both a recursive definition and a defining subset expansion formula. In this article, ...

Topological indices (TIs) play a crucial role in studying graphene's structure as mathematical functions mapping molecular graphs to real numbers, capturing their topological characteristics. To ...

In this paper we deal a classical problem, degree restricted spanning trees for series-parallel graph. Our general goal is to prove the NP-completeness of restricted degree spanning trees for ...
