The reviewers are quite tough and thorough and the submission workflow procedures are well organized.

So slow, so slow, even though it is a math journal, it is only in the third tier of the Chinese Academy of Sciences. The speed of review seems to be submitting to a top-tier journal.

The following text translates to: "Mathematical optimization field is quite recognized for its high requirements for algorithm innovation. Due to the difficulty of publication and low circulation, it is becoming more and more unpopular. After two major revisions and two minor revisions, the paper was accepted by two reviewers. The review comments were quite professional, making the editing process challenging and quite tedious."

Recently, I changed one article and changed it three times. From the submission to the acceptance of a few days, the journal was published very slowly. Generally, the article hangs online for a long time, almost a year?However, editors and reviewers are very responsible and the journals handle manuscripts very professionally.To add, this journal is now published eight times a year, about eight in each issue.
