In this article, we show that the disjoint union C2k ∪ C2j+1 of cycles C2k and C2j+1 (k≥2, j≥1, (k,j)≠(2,1)) is harmonious.

Due to unavoidable circumstances, journal publications experienced a temporary suspension, during which misleading domains such as https://combinatorialpress.com/um/ (see in this all journals are clone) and www.combinatorialmath.com appeared. While the latter remained dormant, the former, under the guise of Utilitas Mathematica, disseminated unverified content that does not uphold the true legacy of Utilitas Mathematica.
Paper Selection and Publishing Process
a) Submission Acknowledgement
When you submit a manuscript online, you will receive a submission acknowledgment letter sent by the online system automatically. For email submission, the editor or editorial assistant sends an e-mail confirmation to the submission’s author within one to three working days. If you fail to receive this confirmation, please check your bulk email box or contact the editorial assistant.
b) Basic Review
The editor or editorial assistant determines whether the manuscript fits the journal’s focus and scope. Next, a check for the similarity rate is done using CrossCheck, powered by iThenticate. Any manuscripts out of the journal’s scope or containing plagiarism, including self-plagiarism, are rejected.
c) Peer Review
At least two peer-reviewers will review every submitted paper. Reviewers are unaware of the authors' identity, and authors are also unaware of the identity of reviewers (double-blind review method). Reviewing process will consider novelty, objectivity, method, scientific impact, conclusion, and references. Reviewers' comments are then sent to the corresponding author for necessary actions and responses. The suggested decision will be evaluated in an editorial board meeting. Afterward, the editor will send the final decision to the corresponding author. The review process may take four to six weeks.
d) Decision is Made
The decision to accept or reject an article is based on the suggestions of reviewers. If differences of opinion occur between reviewers, the editor-in-chief will weigh all comments and arrive at a balanced decision based on all comments, or the second round of peer review may be initiated.
e) Notification of the Result of Review
The result of the review will be sent to the corresponding author and forwarded to other authors.
f) Publication Notice
The authors and readers will be notified and invited to visit our website for the newly published articles.
