Overview

Top Research Topics at Computational Complexity?

The primary areas of discussion in the journal are Discrete mathematics, Combinatorics, Function (mathematics), Polynomial and Time complexity. Computational Complexity focuses on Discrete mathematics but the discussions also offer insight into other areas such as Mathematical proof and Constant (mathematics). Proof complexity is a major topic of Mathematical proof research presented in Computational Complexity.

Computational Complexity holds forums on Combinatorics that merges themes from other disciplines such as Computational complexity theory and Algebraic number. The in-depth study on Function (mathematics) also explores topics in the intersecting field of Communication complexity. The Polynomial study featured in it draws connections with the study of Finite field.

The study on Boolean function featured in Computational Complexity expounds on the topic of Parity function in particular. It focuses on Degree (graph theory) as well as the interrelated topic of Field (mathematics).

The previous edition focused in particular on these issues:

The main research concerns discussed in Computational Complexity are Combinatorics, Discrete mathematics, Degree (graph theory), Field (mathematics) and Binary logarithm. While Computational Complexity primarily focused on Combinatorics, it also opened dialogues on the discipline of Bounded function. The work on Discrete mathematics tackled in the journal brings together disciplines like Logarithm, Mathematical proof and Algebraic number.

Computational Complexity facilitates discussions on Mathematical proof that incorporate concepts from other fields like Hankel matrix, Commutative property, Multiplication and Associative property. In Computational Complexity, Image (category theory), Prime (order theory), Ring (mathematics), Pigeonhole principle and Finite field are investigated in conjunction with one another to address concerns in Field (mathematics) research. It explores research in Binary logarithm alongside concepts in Quadratic growth and other areas of study in Quantum information, Exponential function and Gas meter prover.

  • Nullstellensatz Size-Degree Trade-offs from Reversible Pebbling (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 Computational Complexity (based on the number of publications) are:

  • Oded Goldreich (13 papers) absent at the last edition,
  • Toniann Pitassi (13 papers) published 1 paper at the last edition,
  • Russell Impagliazzo (12 papers) absent at the last edition,
  • Amir Shpilka (11 papers) absent at the last edition,
  • Ronen Shaltiel (11 papers) published 1 paper 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 Computational Complexity (based on the number of publications) are:

  • Weizmann Institute of Science (38 papers) absent at the last edition,
  • University of Toronto (28 papers) published 1 paper at the last edition,
  • Princeton University (26 papers) absent at the last edition,
  • Tel Aviv University (26 papers) published 1 paper at the last edition,
  • Technion – Israel Institute of Technology (24 papers) published 1 paper 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, 13.33% of publications had an unrecognized affiliation. Out of the publications with recognized affiliations, 30.77% were posted by at least one author from the top 10 institutions publishing in the journal. Another 23.08% included authors affiliated with research institutions from the top 11-20 affiliations. Institutions from the 21-50 range included 30.77% of all publications and 15.38% 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.
