Overview

Top Research Topics at Constraints - An International Journal?

The concepts of Mathematical optimization, Constraint satisfaction, Constraint programming, Algorithm and Constraint satisfaction problem are tackled in Constraints - An International Journal. It connects the study in Mathematical optimization with the closely related area of Scheduling (computing). The majority of Scheduling (computing) studies are focused on the issues of Job shop scheduling.

Constraint satisfaction studies presented in Constraints - An International Journal focus on topics such as Constraint logic programming, Local consistency, Constraint satisfaction dual problem, Hybrid algorithm (constraint satisfaction) and Binary constraint. It focuses on different Constraint logic programming studies like Constraint learning and Constraint graph. Topics in Constraint programming explored in it were investigated in conjunction with research in Programming language, Theoretical computer science, Combinatorial optimization and Artificial intelligence.

The presentations discussing Algorithm offer insights in topics such as Search algorithm, Boolean satisfiability problem, Satisfiability, Time complexity and Linear programming. Constraint satisfaction problem research featured in Constraints - An International Journal incorporates concerns from various other topics such as Discrete mathematics and Backtracking.

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 Constraints - An International Journal (based on the number of publications) are:

  • Pascal Van Hentenryck (21 papers) absent at the last edition,
  • Peter J. Stuckey (21 papers) absent at the last edition,
  • Mark Wallace (12 papers) absent at the last edition,
  • Nicolas Beldiceanu (9 papers) absent at the last edition,
  • Brahim Hnich (9 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 Constraints - An International Journal (based on the number of publications) are:

  • University College Cork (30 papers) absent at the last edition,
  • University of Melbourne (24 papers) absent at the last edition,
  • Brown University (16 papers) absent at the last edition,
  • French Institute for Research in Computer Science and Automation (15 papers) absent at the last edition,
  • Carnegie Mellon University (13 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 2021 edition, 0.00% 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 33.33% of all publications and 66.67% 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.
