Instances for 2D Strip Packing Problem

This dataset coprises instances for 2-dimensional strip packing (2SP) problem. Test Instances Collections of the instances:• dataset1 - 1st set of random instances (training).• dataset2 - 2nd set of random instances (validation). The instances are collected in the following files # instances comments 1. dataset1.zip size ~6.8MB 2. dataset2.zip size ~6.8MB File Name Convention• 0.in - 99.in -- dataset1 instances with n=10 items,• 100.in - 199.in -- dataset1 instances with n=20 items,• 200.in - 299.in -- dataset1 instances with n=50 items,• 300.in - 399.in -- dataset1 instances with n=100 items,• 400.in - 499.in -- dataset1 instances with n=200 items,• 500.in - 599.in -- dataset1 instances with n=500 items,• 600.in - 699.in -- dataset1 instances with n=1000 items,• 700.in - 799.in -- dataset1 instances with n=2000 items,• 800.in - 899.in -- dataset1 instances with n=5000 items,• 900.in - 999.in -- dataset1 instances with n=10000 items,• 1000.in - 1099.in -- dataset2 instances with n=10 items,• 1100.in - 1199.in -- dataset2 instances with n=20 items,• 1200.in - 1299.in -- dataset2 instances with n=50 items,• 1300.in - 1399.in -- dataset2 instances with n=100 items,• 1400.in - 1499.in -- dataset2 instances with n=200 items,• 1500.in - 1599.in -- dataset2 instances with n=500 items,• 1600.in - 1699.in -- dataset2 instances with n=1000 items,• 1700.in - 1799.in -- dataset2 instances with n=2000 items,• 1800.in - 1899.in -- dataset2 instances with n=5000 items,• 1900.in - 1999.in -- dataset2 instances with n=10000 items.File FormatInstance files are text files with data in the following order:- 1st line: W LB- 2nd line: n- lines 3 to n+2 - item data (in the order): width heightwhere:n - number of items,LB - height Lower Bound,W - width of the strip.
