The data generation scheme builds on the base case &nbsp;that consists of uncorrelated instances&nbsp;described in&nbsp;http://home.ku.edu.tr/~moolibrary/. Here, the objective function coefficients (knapsack, assignment) &nbsp;and&nbsp; constraint coefficients (knapsack)&nbsp;&nbsp;display certain levels of positive correlation. The details of the data generation scheme used is given in the document description.pdf. &nbsp;</p> <p>Knapsack problem instances&nbsp;&nbsp;have&nbsp;three objective functions, &nbsp; 25, 50, 75, 100 objects, 4 levels of correlation&nbsp;(10 in each category).</p> <p>Assignment problem instances&nbsp;&nbsp;have&nbsp;three objective functions, &nbsp;5,10,...,50&nbsp;objects, 4 levels of correlation&nbsp;(10 in each category).</p></description> </descriptions> </resource>
