The reviewer is quite professional and asked me to supplement several experiments.

@6ye Just because the quality of a special issue is good, doesn't mean the entire journal is a good journal. (Poor countries also have billionaires) You should see for yourself how many special issues this magazine has organized in a year.

According to the suggestions of the reviewers, make modifications point by point and reply earnestly, finally there is hope! Suggestions for the precious ones, polish the language well and use references from recent years if possible, and ensure a clear logical structure....... Wish everyone good luck!

The advantages and disadvantages of MDPI journals are quite obvious. The speed is indeed guaranteed, and rejections are quickly responded to. The submission to acceptance cycle is generally around 2-3 months.

Excuse me, did you submit it? Or why did you choose to submit to this trashy journal? Axioms have a special issue that was submitted by a prominent scholar from China. You can find it at https://www.mdpi.com/2075-1680/11/5/190.

This is what is called "insiders understand the tricks, while outsiders enjoy the spectacle."

MDPI's mathematics journals are nothing more than predatory journals. They publish a large number of articles per year and organize numerous special issues (often receiving spam emails for related themed special issues). I have read several articles from a special issue of Axioms, and they are completely shoddily made (with numerous printing errors and some derivations completely incorrect), yet they still manage to get published! Compared to traditional mathematics journals (such as Springer and Project Euclid's mathematics journals), they simply manipulate the impact factor to appear impressive to non-experts!

Hello, may I ask what topic your article is about? How is the entire review process like? How long is the response time for the first review? Thank you!

The first review is back with minor revisions. The editor is extremely friendly, and the reviewer is particularly responsible.
