Additional Editor Comments:

The paper is well-organized with solid contribution. The results have been given clearly and sufficiently. All the reviewers' comments show that the paper is acceptable after a minor revision. In particular, some typos in the paper should be corrected and a proof reading is helpful to improve the quality of the presentation. The motivation and the background of the study should also be highlighted with more details where including more reference to support the motivation may be a proper approach. Therefore, a minor revision is needed to respond all the comments.

5. Review Comments to the Author

Please use the space provided to explain your answers to the questions above. You may also include additional comments for the author, including concerns about dual publication, research ethics, or publication ethics. (Please upload your review as an attachment if it exceeds 20,000 characters)

Reviewer #1: This is a detailed paper that proposes a new improved artificial bee colony (ABC) method for multi-period uncertain portfolio selection. The explanation on how to improve it are well presented. However, when compared to other techniques, the choice of ABC is not insufficiently discussed. By introducing CPT for the first time, the abbreviations should be used correctly to improve the article.

Reviewer #2: This paper discusses a multi-period uncertain portfolio selection model with a prospect utility function and designs a new artificial bee colony algorithm by combining the sine cosine search method. The paper is overall enjoyable, and the originality of this paper is high. However, the reviewer still has the following comments which need to be addressed.

1. This paper is advised to revise the literature review section, including these related references. The authors can consider including the following research works to enrich the literature study.

(i)https://www.sciencedirect.com/science/article/abs/pii/S1568494615005955/

(ii) https://link.springer.com/article/10.1007/s12652-017-0478-4

2. This paper introduces the ABC algorithm and proposes a novel improved method. However, different algorithms have different applications. The author should introduce the application of the ABC algorithm in the field of the portfolio.

3.Some grammar errors should be noticed and updated as formal English writing style.

Reviewer #3: This manuscript describes an improved artifificial bee colony algorithms for a multi-period uncertain portfolio selection problem. Numerical results prove the effectiveness of the algorithm under reasonable assumptions, and data analysis is performed appropriately. It is interesting and organized well. The manuscript can be accepted after correcting grammartical、spelling errors.

For example:

1.After definition 3, in “provided that at least one of the two integrals is fifinite.” here, “provided” should be “Provided”.

2.In equation (26) has been given a comma symbol, it should be given a full stop symbol.

3.In line 6, "makes an one-off... " is incorrect.

4.In line 12, "programing" should be “programming”.

5.In the line 10 of second paragraph, the spaces of "returns . For example ," should be deleted.
