The authors’ goal is to demonstrate a new algorithm to improve the process of finding an optimum item of interest, among multiple items of the same type, in an irregularly shaped area. The methodology used by the authors is based on a process of creating a polygon to represent the irregular area and using that to serve as a foundation to solve the problem. They state that this method is less likely to have errors than the more traditional methods. It is an interesting concept and could be of value for solutions such as GPS routing based on differing criteria.

The authors add to the overall knowledge in this area, and they have come up with a different approach that they say is an improvement over previous solution methods. Unfortunately, the manner in which the material is presented makes it difficult to follow and is a deterrent to reading the paper and grasping the concepts therein.

The paper contains numerous grammatical errors, causing it to be difficult at times to understand what the authors are trying to present. Examples include the first sentence in the abstract: “Cloud computing, which takes advantage of sharing resources, provide services to users.” Another phrase from the abstract reads, “It enables user to input an irregular shape.” And again from the abstract, “Our algorithm is proved to be increase the result accuracy.” This type of grammatical error pervades the paper.

The majority of the figures illustrating their concepts are clustered in blocks located in areas unrelated to the text describing them. It is apparent that the authors did not plan to have the figures so far separated from the material discussing them; for example, on page 13, the authors state: “Hence, the distance MINDIST can be defined as below in Figure 8.” However, Figure 8 was back on page 6. This makes it very difficult to follow the paper because it is necessary to flip back and forth between pages to follow the written material and the figures.
