Overview

Top Research Topics at Siam Journal on Optimization?

Siam Journal on Optimization generally zeroes in on subjects such as Mathematical optimization, Applied mathematics, Combinatorics, Algorithm and Discrete mathematics. The Mathematical optimization works featured in the journal incorporate elements from Nonlinear programming and Convex optimization. In Siam Journal on Optimization, researchers investigate the Nonlinear programming study as part of research in the field of Nonlinear system.

It dives deep in exploring the relationship between the study of Convex optimization and Convex function. The study of Mathematical analysis and how it intertwines with concepts under Pure mathematics were explored in the presented Applied mathematics research. In addition to Combinatorics research, it aims to explore topics under Matrix (mathematics), Bounded function, Semidefinite programming and Regular polygon.

Topics in Semidefinite programming explored in Siam Journal on Optimization were investigated in conjunction with research in Semidefinite embedding and Quadratically constrained quadratic program. The studies in Algorithm featured incorporate elements of Function (mathematics) and Rate of convergence. The journal focuses on Interior point method as well as the interrelated topic of Linear programming.

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, 90.53% of publications had an unrecognized affiliation. Out of the publications with recognized affiliations, 33.33% 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 44.44% of all publications and 22.22% 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.
