Top Research Topics at Discrete Applied Mathematics?

Combinatorics, Discrete mathematics, Graph, Algorithm and Vertex (geometry) are among the topics commonly tackled in Discrete Applied Mathematics. It focuses on Combinatorics research which is adjacent to topics in Upper and lower bounds. Pathwidth, Graph power, Bipartite graph, Split graph and Bound graph are all aspects of Discrete mathematics discussed in the journal.

Discrete Applied Mathematics connects research in Graph with the related topic of Conjecture. Most of the works presented in Discrete Applied Mathematics deals with Algorithm but it intersects with the subject of Mathematical optimization. Discrete Applied Mathematics connects the study in Mathematical optimization with the closely related area of Scheduling (computing).

Chordal graph research discussed connects with the study of Treewidth.

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

• Combinatorics
• Algorithm
• Artificial intelligence

The previous edition focused in particular on these issues:

The journal facilitates discussions on Combinatorics, Graph, Unicyclic graphs, Index (economics) and Order (group theory). The research on Combinatorics discussed in the journal draws on the closely related field of Function (mathematics). The work on Graph tackled in the journal brings together disciplines like Chromatic scale and Girth (graph theory).

Chromatic scale research presented in the journal encompasses a variety of subjects, including Grundy number, Conjecture, Class (set theory), Chordal graph and Vertex (geometry). Discrete Applied Mathematics holds forums on Unicyclic graphs that merges themes from other disciplines such as Graph (abstract data type) and Independence number. The research on Order (group theory) tackled can also make contributions to studies in the areas of Signless laplacian, Matrix (mathematics), Diagonal matrix, Eigenvalues and eigenvectors and Spectrum (functional analysis).

The most cited articles from the last journal are:

• Webster sequences, apportionment problems, and just-in-time sequencing (0 citations)
• Four-searchable biconnected outerplanar graphs (0 citations)
• Extremal vertex-degree function index for trees and unicyclic graphs with given independence number (0 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.

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, 33.33% of publications had an unrecognized affiliation. Out of the publications with recognized affiliations, 0.00% were posted by at least one author from the top 10 institutions publishing in the journal. Another 0.00% included authors affiliated with research institutions from the top 11-20 affiliations. Institutions from the 21-50 range included 16.67% of all publications and 83.33% 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.
