Edge‐colored saturated graphs

Journal of Graph Theory, 1987
AbstractA graph G is (k1, k2, …, kt)‐saturated if there exists a coloring C of the edges of G in t colors 1, 2, …, t in such a way that there is no monochromatic complete ki‐subgraph K of color i, 1 ⩽ i ⩽ t, but the addition of any new edge of color i, joining two nonadjacent vertices in G, with C, creates a monochromatic K of color i, 1 ⩽ i ⩽ t.

Extending an edge‐coloring

Journal of Graph Theory, 1990
AbstractWhen can a k‐edge‐coloring of a subgraph K of a graph G be extended to a k‐edge‐coloring of G? One necessary condition is that for all X ⊆ E(G) ‐ E(K), where μi(X) is the maximum cardinality of a subset of X whose union with the set of edges of K colored i is a matching.

Edge-aware color appearance

ACM Transactions on Graphics, 2011
Color perception is recognized to vary with surrounding spatial structure, but the impact of edge smoothness on color has not been studied in color appearance modeling. In this work, we study the appearance of color under different degrees of edge smoothness.

Edge-Coloring Partialk-Trees

Journal of Algorithms, 1996
Summary: Many combinatorial problems can be efficiently solved for partial \(k\)-trees (graphs of treewidth bounded by \(k\)). The edge-coloring problem is one of the well-known combinatorial problems for which no efficient algorithms were previously known, except a polynomial-time algorithm of very high complexity.

Optimal edge‐coloring with edge rate constraints

Networks, 2013
We consider the problem of covering the edges of a graph by a sequence of matchings subject to the constraint that each edge e appears in at least a given fraction r(e) of the matchings. Although it can be determined in polynomial time whether such a sequence of matchings exists or not [Grötschel et al., Combinatorica (1981), 169–197], we show that ...

Color edge detection

Pattern Recognition Letters, 1985
The detection of visually significant edges and boundaries in a natural color image is complicated by inherent noise and correlation between color coordinates. In this letter we present a color edge detector which uses fuzzy set theory to model this imprecision.

Edge Coloring Series Parallel Graphs

Journal of Algorithms, 1995
Abstract We present an algorithm for optimally edge coloring series parallel graphs. We give a linear time implementation, as well as a parallel implementation, of the algorithm that runs in O (log 3 n ) time using O ( n ) processors. The sequential implementation, which is optimal, improves the best-known algorithm. The parallel implementation of
