Thank you for your helpful suggestions.
According to your comments, we have made the following corrections.
- Please highlight your contribution separately.
Yes, we do. We added point-by-point the main contributions at the end of the Introduction section.
- Please indicate the difficulties that have been overcome in solving the
The previous research based on the properties of compact operators or increasing operators. The integral operator defined in this paper is a decreasing operator.
- Please indicate the relevance of the problem by citing literature from
recent years.
Yes, we do. We added three papers in recent years. They focused on TVP of fractional differential equations and concerned with numerical solutions of the problems.
- Please add a conclusion.
Yes, we do. We added the conclusion at the last section.
Reviewer 2 Report
Paper deals with the important question of terminal value problem. The authors considered the idea of the first-order differential equation.
But from my side, I see a few points, which could be updated:
1. Abstract should be extended by the obtained results of the paper.
2. It would be good to add point-by-point the main contributions at the end of the Introduction section.
3. I would suggest working on methods sections to make it better structured, provide comparisons and visualize steps, in a clearer way.
4. The results section should be extended using: 1) numerical results obtained in the paper; 2) limitations of the proposed approach; 3) prospects for future research.
4. The paper hasn’t any Discussions.
5. The paper hasn’t any Conclusions.
6. A lot of references are outdated and unlinked. Please fix it by using 3-5 years old papers in high-impact journals.
7. Paper does not meet guideline format.

Yes, we do. We try to make the proof steps in a clearer way.
- The results section should be extended using: 1) numerical results obtained in the paper; 2) limitations of the proposed approach; 3) prospects for future research.
Thank you for your help. We have done the following
- We presented the iterative scheme of solutions, computed the approximation solutions and draw the figure of the approximation solutions of a TVP, see in Section 4;
- We discussed the limitation of the proposed approach in Section 5;
- We introduced the future research in Section 6.
- The paper hasn’t any Discussions.
We added the Discussion section.
- The paper hasn’t any Conclusions.
We added the Conclusion section.
- A lot of references are outdated and unlinked. Please fix it by using 3-5 years old papers in high-impact journals.
Yes, we do. We added three papers in recent three years.
- Paper does not meet guideline format.
We revised the format.

by
Yuqiang Feng, Qian Pan, Jun Jiang
· Overview of manuscript
The authors presented the application of comparison lemmas, iterative technique, and fixed-point method, to obtain the existence and uniqueness results of solutions for a terminal value problem of first-order differential equation.
· Comments on text
1. New contribution
The authors need to talk about all the new contributions of their study.
· English
The English in this paper is ok but we can see some grammatical issues such as “an terminal value” and so on.
Comments
(a) The authors require to improve the literature review.
(b) This manuscript does not include any discussion or conclusion part. Please provide these sections.
(c) The authors may need to explain more about terminal problem in application.
(d) That would be better if authors can briefly imply to the applications of comparison lemmas, iterative technique and fixed point method.
(e) Please explain the contribution or novelty of this work.
(f) Any numerical simulation to validate the results?
