Overview

Top Research Topics at Journal of Combinatorial Designs?

The aim of the journal is to expand the discussion of research in Combinatorics, Discrete mathematics, Order (group theory), Steiner system and Block size. Journal of Combinatorial Designs focuses on Combinatorics but the discussions also offer insight into other areas such as Type (model theory) and Group (mathematics). The studies on Discrete mathematics discussed can also contribute to research in the domains of Class (set theory), Upper and lower bounds and Partition (number theory).

The journal facilitates the exploration of Orthogonal array in relation to the field of Graeco-Latin square.

  • Combinatorics (99.43%)
  • Discrete mathematics (46.40%)
  • Order (group theory) (15.15%)

What are the most cited papers published in the journal?

  • Cycle decompositions III: Complete graphs and fixed length cycles (165 citations)
  • Covering arrays and intersecting codes (142 citations)
  • Small latin squares, quasigroups, and loops (142 citations)

Research areas of the most cited articles at Journal of Combinatorial Designs:

The main points discussed in the journal articles deal with Combinatorics, Discrete mathematics, Order (group theory), Orthogonal array and Steiner system. In addition to Combinatorics research, the published papers aim to explore topics under Projective space and Group (mathematics). The journal publications about Regular graph, Disjoint sets and Combinatorial design research are fields of study within Discrete mathematics but they also intertwine with concepts in Generalization.

What topics the last edition of the journal is best known for?

  • Combinatorics
  • Algebra
  • Geometry

The previous edition focused in particular on these issues:

The journal tackles a plethora of topics, such as Combinatorics, Steiner system, Block size, Pure mathematics and Automorphism group. The studies in Combinatorics featured incorporate elements of Type (model theory) and Projective plane. The journal addresses concerns in Steiner system which are intertwined with other disciplines, such as Current (mathematics), Isomorphism, Existential quantification and Graph.

The presented studies in Affine invariant fall within the purview of Pure mathematics but it also intertwines with topics in Weight distribution. The research on Automorphism group featured in it combines topics in other fields like Quadratic residue code, Flag (geometry), Reduction (complexity) and Binary number. Disjoint sets research presented in Journal of Combinatorial Designs encompasses a variety of subjects, including Hypergraph and Class (set theory).

The most cited articles from the last journal are:

  • The localization number of designs (5 citations)
  • Graph decompositions in projective geometries (5 citations)
  • Perfect $2$-colorings of Hamming graphs (3 citations)

Papers citation over time

A key indicator for each journal is its effectiveness in reaching other researchers with the papers published at that venue.

The chart below presents the interquartile range (first quartile 25%, median 50% and third quartile 75%) of the number of citations of articles over time.

The top authors publishing in Journal of Combinatorial Designs (based on the number of publications) are:

  • Gennian Ge (24 papers) published 1 paper at the last edition,
  • Marco Buratti (23 papers) published 2 papers at the last edition,
  • Yanxun Chang (22 papers) published 1 paper at the last edition the same number as at the previous edition,
  • Lijun Ji (21 papers) absent at the last edition,
  • Alan C. H. Ling (18 papers) absent at the last edition.

The overall trend for top authors publishing in this journal is outlined below. The chart shows the number of publications at each edition of the journal for top authors.

Only papers with recognized affiliations are considered

The overall trend for top affiliations publishing in this journal is outlined below. The chart shows the number of publications at each edition of the journal for top affiliations.

Publication chance based on affiliation

The publication chance index shows the ratio of articles published by the best research institutions in the journal edition to all articles published within that journal. The best research institutions were selected based on the largest number of articles published during all editions of the journal.

The chart below presents the percentage ratio of articles from top institutions (based on their ranking of total papers).Top affiliations were grouped by their rank into the following tiers: top 1-10, top 11-20, top 21-50, and top 51+. Only articles with a recognized affiliation are considered.

During the most recent 2021 edition, 0.00% of publications had an unrecognized affiliation. Out of the publications with recognized affiliations, 24.39% were posted by at least one author from the top 10 institutions publishing in the journal. Another 2.44% included authors affiliated with research institutions from the top 11-20 affiliations. Institutions from the 21-50 range included 36.59% of all publications and 36.59% were from other institutions.

Returning Authors Index

A very common phenomenon observed among researchers publishing scientific articles is the intentional selection of journals they have already attended in the past. In particular, it is worth analyzing the case when the authors participate in the same journal from year to year.

The Returning Authors Index presented below illustrates the ratio of authors who participated in both a given as well as the previous edition of the journal in relation to all participants in a given year.

Returning Institution Index

The graph below shows the Returning Institution Index, illustrating the ratio of institutions that participated in both a given and the previous edition of the conference in relation to all affiliations present in a given year.

The experience to innovation index

Our experience to innovation index was created to show a cross-section of the experience level of authors publishing in a journal. The index includes the authors publishing at the last edition of a journal, grouped by total number of publications throughout their academic career (P) and the total number of citations of these publications ever received (C).

The group intervals were selected empirically to best show the diversity of the authors' experiences, their labels were selected as a convenience, not as judgment. The authors were divided into the following groups:

  • Novice - P < 5 or C < 25 (the number of publications less than 5 or the number of citations less than 25),
  • Competent - P < 10 or C < 100 (the number of publications less than 10 or the number of citations less than 100),
  • Experienced - P < 25 or C < 625 (the number of publications less than 25 or the number of citations less than 625),
  • Master - P < 50 or C < 2500 (the number of publications less than 50 or the number of citations less than 2500),
  • Star - P ≥ 50 and C ≥ 2500 (both the number of publications greater than 50 and the number of citations greater than 2500).

The chart below illustrates experience levels of first authors in cases of publications with multiple authors.
