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.本文献https://doi.org/10.1016/j.omega.2021.102392 中采用了4组真实世界测试实例，如下所示。这些实例可为其他研究者开发求解掩模设计问题（Mask Design Problem, MDP）这一优化问题的替代解法提供支撑。该问题产生于使用配备可配置狭缝单元的光谱仪器，于天空中选取观测视场与待研究恒星天体的场景中。研究者可针对每组实例获取对应的".dat"格式文件，该文件用于确定星表中所有恒星在天空中约1平方度范围内的位置。每组实例还附带了上述文献中提出的方法所得到的求解结果。其余细节（如计算耗时等）均已在原文中完整说明。
