The journal publications are organized to reinforce research efforts on Combinatorics, Discrete mathematics, Graph, Set (abstract data type) and Conjecture. Aside from discussions in Combinatorics, the most cited articles also deal with the subject of Projective plane which intersects with Collineation disciplines. In addition to Discrete mathematics research, the most cited articles aim to explore topics under Partition (number theory) and Degree (graph theory).

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

  • Artificial intelligence
  • Combinatorics
  • Algebra

The previous edition focused in particular on these issues:

Combinatorics, Property (philosophy), Graph, Structure (category theory) and Conjecture are among the topics commonly tackled in European Journal of Combinatorics. The studies on Combinatorics discussed can also contribute to research in the domains of Intersection and Generalized quadrangle. The journal explores issues in Property (philosophy) which can be linked to other research areas like Zero (complex analysis), Composite number and Modulo.

European Journal of Combinatorics holds forums on Graph that merges themes from other disciplines such as Disjoint sets, Simple (abstract algebra) and Automorphism group, Automorphism. In addition to Structure (category theory) research, European Journal of Combinatorics aims to explore topics under Type (model theory), Finite set, Real vector, Exterior algebra and Adjacency matrix. Conjecture research featured in it incorporates concerns from various other topics such as Orientation (graph theory), Colored, Order (ring theory) and Edge (geometry).

The most cited articles from the last journal are:

  • Linear Turán numbers of acyclic triple systems (1 citations)

  • Hamilton Cycles in the Semi-random Graph Process (1 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 European Journal of Combinatorics (based on the number of publications) are:

  • Yasushi Kiyoki (104 papers) absent at the last edition,
  • Bernhard Thalheim (46 papers) absent at the last edition,
  • Hannu Jaakkola (32 papers) absent at the last edition,
  • Shiori Sasaki (29 papers) absent at the last edition,
  • Anneli Heimbürger (25 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 top affiliations publishing in European Journal of Combinatorics (based on the number of publications) are:

  • University of Illinois at Urbana–Champaign (32 papers) absent at the last edition,
  • University of Cambridge (27 papers) absent at the last edition,
  • Centre national de la recherche scientifique (26 papers) absent at the last edition,
  • Massachusetts Institute of Technology (25 papers) absent at the last edition.

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 2022 edition, 23.53% of publications had an unrecognized affiliation. Out of the publications with recognized affiliations, 15.38% were posted by at least one author from the top 10 institutions publishing in the journal. Another 7.69% included authors affiliated with research institutions from the top 11-20 affiliations. Institutions from the 21-50 range included 15.38% of all publications and 61.54% 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.
