    <description descriptionType="Abstract">&lt;p&gt;This&amp;nbsp;data set contains problem instances for multiobjective knapsack and assignment problems with three objective functions. The data generation scheme builds on the base case &amp;nbsp;that consists of uncorrelated instances&amp;nbsp;described in&amp;nbsp;http://home.ku.edu.tr/~moolibrary/. Here, the objective function coefficients (knapsack, assignment) &amp;nbsp;and&amp;nbsp; constraint coefficients (knapsack)&amp;nbsp;&amp;nbsp;display certain levels of positive correlation. The details of the data generation scheme used is given in the document description.pdf. &amp;nbsp;&lt;/p&gt;

&lt;p&gt;Knapsack problem instances&amp;nbsp;&amp;nbsp;have&amp;nbsp;three objective functions, &amp;nbsp; 25, 50, 75, 100 objects, 4 levels of correlation&amp;nbsp;(10 in each category).&lt;/p&gt;

&lt;p&gt;Assignment problem instances&amp;nbsp;&amp;nbsp;have&amp;nbsp;three objective functions, &amp;nbsp;5,10,...,50&amp;nbsp;objects, 4 levels of correlation&amp;nbsp;(10 in each category).&lt;/p&gt;</description>
