    <dc:description>This is the data for the paper &quot;The gradual minimum covering location problem&quot;, available at:

https://www.tandfonline.com/doi/full/10.1080/01605682.2022.2056533

There are 180 .csv fies in the data, containing 90 &quot;nodes&quot; files, denoted by &quot;n_x_nodes&quot;, and 90 &quot;population&quot; files, denoted by &quot;n_x_population&quot;, where n shown the number of nodes (n = 100, 200, 300, 400, 500, 1000, 2000, 5000, 10000) and x represents the instance ID (x = 1, ..., 10). The same instance file can be used for the two type of problems where p (the number of facilities) is 5 or 10. 
The &quot;nodes&quot; files represents the coordiante of the nodes, i.e., the 100-1-nodes contains 100 coordinates, each in one column, where the value in the first (second) row represents the x- (y-) coordinate of the node in a 200 by 200 grid. The &quot;populaiton&quot; files, contains the populaiton c of the respective nodes, that are numbers between 1 to 100.</dc:description>
