POMS

Description : This package includes the JAVA code of the POMS algorithm [1] for the multiset selection problem (i.e., maximizing functions over the integer lattice) with a size constraint. This is an extension of our previous POSS algorithm [2] for the subset selection problem (i.e., maximizing functions over subsets) with a size constraint. POMS uses a randomized iterative procedure to solve the bi-objective reformulation of the original problem: maximizing the objective function and minimizing the multiset size. A Readme file and an example file are included in the package. In the 'Example.java', you will find an example of using this code for the application of budget allocation.
