TOP is Q1 in Discrete Mathematics and Combinatorics (rank 9 of 99), Q2 in Information Systems and Management (rank 74 of 222) and Q2 in Modeling and Simulation (rank 157 of 397), by CiteScore 2025. It is ranked in 4 subject areas in all.
TOP is indexed in the Science Citation Index Expanded, so it may have a Journal Impact Factor in Clarivate's Journal Citation Reports. JCR is paid, so check it for the current value. The closest free measure is its Scopus CiteScore 3.3, which places it in quartile Q1 at the 91st percentile of its subject. Its SCImago Journal Rank (SJR, a free Scopus-based metric) is 0.438, quartile Q2, with an H-index of 35.

h-index, i10-index and 2-year mean citedness are open, licence-clear metrics from OpenAlex — not a proprietary impact factor. The subject rank counts only journals that OpenAlex has a figure for; it is not a Scopus or Clarivate ranking. Updated 2026-10-14.
In its latest 99 research articles (2022–2026), authors are most often from Spain (27.6%), Brazil (7.7%) and China (7.6%).
Countries are counted fractionally, so a paper by authors from two countries counts half to each.
Scopus status: Active. 1 retracted paper is recorded (1 per 1,000 papers). The Problematic Paper Screener flags none of its papers. These are indicators to check, not findings against the journal.
Retractions from OpenAlex; flags from the Problematic Paper Screener (Cabanac, Labbé & Magazinov, CC BY), 2026-09-21 export. A flag marks a paper for a closer look; it is not a finding against the journal.
Index data is curated from public sources (Scopus, Web of Science, ABDC, FT50, UT Dallas, DOAJ). CiteScore and quartiles reflect the latest available Scopus release. Always verify a journal's current status on its official source before submitting.
