PORM

Description: This package includes the JAVA code of the PORM algorithm [1] for minimizing the ratio f/g of two monotone set functions. It uses a randomized iterative procedure to solve the bi-objective reformulation of the original problem: minimizing f and maximizing g. 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 F-measure maximization in information retrieval.
