1538–1558. The overall rank of SIAM Journal on Discrete Mathematics is 4640. International Scientific Journal & Country Ranking. If we base our results on a weaker assumption (the ETH), they imply that k-Coloring cannot be solved in time no(cw), even on instances with O(log n) colors. We hope this content on epidemiology, disease modeling, pandemics and vaccines will help in the rapid fight against this global problem. Thus, if the SETH is true, 2k - 2 is the “correct” base of the exponent for every fixed k. Along the way, we also consider the complexity of k-Coloring parameterized by the related parameter modular treewidth (mtw). Journal Self-citation is defined as the number of citation from a journal citing article to articles published by the same journal.

Discrete Mathematics provides a common forum for significant research in many areas of discrete mathematics and combinatorics. The purpose is to have a forum in which general doubts about the processes of publication in the journal, experiences and other issues derived from the publication of papers are resolved. The Perspectives section features expository articles accessible to a broad audience that cast new light or present unifying points of view on well-known or insufficiently-known topics. The SJR is a size-independent prestige indicator that ranks journals by their 'average prestige per article'. External citations are calculated by subtracting the number of self-citations from the total number of citations received by the journal’s documents. Scimago Journal & Country Rank. The journal's focus is primarily theoretical rather than empirical, but the editors welcome papers that evolve from or have potential application to real-world problems. menu. The SIAM Journal on Discrete Mathematics publishes research articles on a broad range of topics from pure and applied mathematics including combinatorics and graph theory, discrete optimization and operations research, theoretical computer science, and coding and communication theory.

Discrete Mathematics provides a common forum for significant research in many areas of discrete mathematics and combinatorics. International Scientific Journal & Country Ranking. I. Scimago Journal & Country Rank. menu. The set of journals have been ranked according to their SJR and divided into four equal groups, four quartiles. It measures the scientific influence of the average article in a journal, it expresses how central to the global scientific discussion an average article of the journal is. This is a very well-studied problem that becomes highly intractable when the number of colors k is large. The two years line is equivalent to journal impact factor ™ (Thomson Reuters) metric. The Turán Number of Berge-$K_4$ in 3-Uniform Hypergraphs, Sparse Hypergraphs with Applications to Coding Theory, Finer Tight Bounds for Coloring on Clique-Width, Minimal Cohen--Macaulay Simplicial Complexes, Hitting Minors on Bounded Treewidth Graphs. journal self-citations removed) received by a journal's published documents during the three previous years. SJR is a measure of scientific influence of journals that accounts for both the number of citations received by a journal and the importance or prestige of the journals where such citations come from However, much less is known on its complexity for small, concrete values of k. In this paper, we completely determine, under the Strong Exponential Time Hypothesis (SETH), for any fixed constant k, the complexity of k-Coloring parameterized by clique-width. It is based on the idea that 'all citations are not created equal'. The chart shows the evolution of the average number of times documents published in a journal in the past two, three and four years have been cited in the current year. Among the fields covered by Discrete Mathematics are graph and hypergraph theory, enumeration, coding theory, block designs, the combinatorics of partially ordered sets, extremal set theory, matroid theory, algebraic combinatorics, discrete geometry, matrices, and discrete probability theory.
