The journal has recently started to retract a large number of articles. I wonder what's going on? Can someone who knows come out and explain?

May I ask what's going on with my paper "Reviews Completed" after a month?

You're right, after flipping through the papers in this journal, many of them lack high innovativeness. A lot of them just made a slight innovation on a few points.

A highly recognized publication in the industry, I wonder why the Chinese Academy of Sciences has classified it into the fourth tier?

Very slow, it took me a year to find reviewers for my paper.

The submission status "Editor Assignment Pending" has been going on for a month now. Who else is experiencing the same? Does this mean it has not been sent for external review yet?

Combination Optimization is a specialized journal, with the chief editor and editorial board mostly consisting of Americans. The review process is also mostly conducted by American teachers. The journal has a narrow focus, accepting articles that involve mathematical derivations as well as those in the field of production optimization. In comparison to other journals, its scope of acceptance is limited, unlike broad categories such as materials and energy, which accept any relevant articles and therefore have a high impact factor. This leads to fewer citations and a lower ranking for this journal. The proportion of Chinese submissions is small, and the journal emphasizes fundamental research rather than practical applications. It takes approximately seven to eight months from submission to publication. If one article is accepted, it can be used to replace two articles from other major journals, making it eligible for a Ph.D. application at the University of Minnesota.

Combination optimization of corresponding journals, high-quality journals in operations research, mathematics field, comparably low attention rate.

The translation of the text "组合优化领域老牌期刊" into English is "well-established journal in the field of combinatorial optimization."

The paper does not mention any funding sources, the authors do not include foreigners or multiple affiliations, and they do not recommend reviewers they know. It is a regular submission, and the journal is relatively fair. Even Ph.D. candidates without strong connections can submit their papers. This has been tested, and the journal does not prioritize titles or affiliations.

One of the excellent journals in the field of combinatorial optimization, it leans towards mathematical theory deduction and is relatively difficult. This journal hardly accepts articles that are purely application-based or framework-based (perhaps the editor-in-chief considers these to be myths or fantasies, but many top-tier journals are very fond of framework and application-based articles, such as those that construct models, propose frameworks, improve algorithms, etc.). It accepts more basic research articles, which leads to low citation rates because they involve mathematical deduction, which many people find dull or difficult to understand. Consequently, the journal's impact factor is also low. However, the articles published in this journal have guaranteed quality. The review experts for this journal are all mathematics experts (to my knowledge, many journals randomly select reviewers from a system, including students reviewing articles, even for many top-tier journals. This is the reason why acceptance is often dependent on luck. This journal uses its own pool of experts and does not accept author-recommended reviewers). If one has academic aspirations and does not excessively focus on the journal's impact factor and ranking, this journal is a good choice. It can serve as a representation of one's research value and achievements. The review process is also not slow, with a first decision given within two months. Our research group has included this journal in the recommended publishing list along with many high-ranking journals. If an article is accepted, a reward of 10,000 yuan will be given. However, currently, no one has successfully published in this journal, and the reasons for rejection are usually due to the article being too focused on frameworks and applications.

The journal is very good and suitable for all bloggers to submit articles. This journal is in the field of mathematics and also accepts articles on optimization applications. The editor-in-chief is very meticulous, carefully verifying every piece of data and formula. The journal does not require too much innovation, only the solution to one or a few optimization problems is needed, but it must be practical. The only drawback is that it takes a long time, with at least a two-month interval between each revision. The journal is not well-known and can be considered as one of the hidden gems in the journal world. It focuses on running the journal steadily without competing with others. Those who are not in a hurry to graduate can give it a try.

It is not very slow, but super slow. The manuscript was rejected after 12 months for the first review, without making any revisions. Oh well, you should think carefully when submitting your paper.

The quasi-mainstream journal in the field of optimization is considered a second-rate journal.
