MDP instances

Here are the four real-world instances used in the article https://doi.org/10.1016/j.omega.2021.102392 These instances help other researcher to develop alternative approaches to solve an optimization problem called "Mask Design Problem" (MDP). This problem appears when selecting the field of view and the stellar objects to study in the sky by using a instrument in spectroscopy with a configurable slit unit. The researcher will find here a ".dat" file for each instance that determines the position of all the starts in a catalogue, around one degree square in the sky. For each instance there is also the solution found by the approach in https://doi.org/10.1016/j.omega.2021.102392. Other details (like the computational time, etc) are reported in the article itself.

本文中提及的四个现实世界实例，可参见https://doi.org/10.1016/j.omega.2021.102392。这些实例有助于其他研究者开发解决名为“掩模设计问题”（Mask Design Problem，简称MDP）的优化方法的替代方案。该问题出现在使用具有可配置狭缝单元的光谱仪器选择天空中的视场和恒星对象进行研究时。研究者将在此找到每个实例对应的“.dat”文件，该文件确定了目录中所有恒星的位置，范围约为天空中的一个平方度。对于每个实例，还提供了由https://doi.org/10.1016/j.omega.2021.102392中所述方法找到的解决方案。其他细节（如计算时间等）详见文章本身。
