Overview

Top Research Topics at Discrete and Computational Geometry?

The objective of the journal is to combine knowledge in the areas of Combinatorics, Discrete mathematics, Regular polygon, Polytope and Upper and lower bounds. Combinatorics research presented in it encompasses a variety of subjects, including Plane (geometry), Convex hull and Convex set. The study on Plane (geometry) presented in Discrete and Computational Geometry intersects with subjects under the field of Point (geometry).

It focused on Convex hull research but expanded to cover Convex polytope. Some problems in Convex set that were presented in the journal overlapped with concepts under Convex combination, Subderivative and Convex analysis. It explores topics in Discrete mathematics which can be helpful for research in disciplines like Finite set, Simple (abstract algebra), Bounded function and Hyperplane.

The main emphasis of Discrete and Computational Geometry is the subject of Regular polygon, focusing on Convex body.

  • Combinatorics (98.75%)
  • Discrete mathematics (35.58%)
  • Regular polygon (14.22%)

What are the most cited papers published in the journal?

  • Topological Persistence and Simplification (1217 citations)
  • Computing Persistent Homology (1131 citations)
  • Stability of Persistence Diagrams (917 citations)

Research areas of the most cited articles at Discrete and Computational Geometry:

The journal articles investigate studies in Combinatorics, Discrete mathematics, Plane (geometry), Upper and lower bounds and Polytope. In particular, the Combinatorics works presented in the most cited papers emphasize discussions on Time complexity. The most cited papers facilitate discussions on Discrete mathematics that incorporate concepts from other fields like Simple (abstract algebra), Hyperplane and Bounded function.

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

  • Combinatorics
  • Geometry
  • Algebra

The previous edition focused in particular on these issues:

The aim of the journal is to expand the discussion of research in Combinatorics, Polytope, Regular polygon, Dimension (graph theory) and Upper and lower bounds. The studies tackled, which mainly focus on Combinatorics, apply to Convex body as well. Discrete and Computational Geometry focuses on Polytope but the discussions also offer insight into other areas such as Boundary (topology), Unimodular matrix, Integer and Lattice (group).

The research on Regular polygon featured in it combines topics in other fields like Finite set and Polygon. Dimension (graph theory) study tackled is connected to the field of Space (mathematics). Discussions in the journal are anchored in the subject of Conjecture and the similar topic of Degree (graph theory).

The most cited articles from the last journal are:

  • Symmetric Non-Negative Forms and Sums of Squares (13 citations)
  • The Geometry of Synchronization Problems and Learning Group Actions (12 citations)
  • On Recovery Guarantees for One-Bit Compressed Sensing on Manifolds (9 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 Discrete and Computational Geometry (based on the number of publications) are:

  • Micha Sharir (79 papers) published 1 paper at the last edition, 2 less than at the previous edition,
  • János Pach (36 papers) absent at the last edition,
  • Boris Aronov (35 papers) published 1 paper at the last edition the same number as at the previous edition,
  • Herbert Edelsbrunner (34 papers) published 1 paper at the last edition the same number as at the previous edition,
  • Imre Bárány (30 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 Discrete and Computational Geometry (based on the number of publications) are:

  • Courant Institute of Mathematical Sciences (94 papers) absent at the last edition,
  • Hungarian Academy of Sciences (77 papers) absent at the last edition,
  • Charles University in Prague (75 papers) published 1 paper at the last edition, 1 less than at the previous edition,
  • Tel Aviv University (73 papers) published 1 paper at the last edition, 2 less than at the previous edition,
  • University of Illinois at Urbana–Champaign (70 papers) published 2 papers at the last edition, 5 less than at the previous 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, 4.93% of publications had an unrecognized affiliation. Out of the publications with recognized affiliations, 14.81% were posted by at least one author from the top 10 institutions publishing in the journal. Another 9.63% included authors affiliated with research institutions from the top 11-20 affiliations. Institutions from the 21-50 range included 27.41% of all publications and 48.15% 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.
