My problem is in trying to solve a Binary Integer Program through Java. I want to run a series of experiments and an integral component of these experiments is to solve an integer program where the variables are constrained to be between 0 and 1.
In the past I have solved such problems in MatLab, with the function bintprog. In the search for such a function (or class? I’m very new to Java) to use in Java, I have come up empty handed.
Is there a Java library available to solve Integer Programs that has really good documentation?
In my search, I have seen suggestions to use a package called LP_Solve that has had a Java wrapper built around it, and a similar wrapper built for a package called GLPK (wrappers here and here) (which I have used before). The problem with these tools is that they are not strictly designed for Java, and thusly, lack the kind of documentation that I feel I need, and even worse have complicated instructions to even begin using them in my own code. As I am currently learning the Java language I am wondering if there are any really good packages available to solve Binary Integer Programs, Mixed Integer Linear Programs, or just Integer Programs from my own Java code.
As a side note, I really do not want to switch to another language because I am building off of past code and classes that perform the tasks I desire.
LP_Solve with the Java wrapper is what I will be using. It is a free Mixed Integer Linear Program solver. LP_Solve for Java is very easy to install following these instructions. Included in the packages you download are files with lots of example code, which I have found useful. The only part of the installation that slowed me down was having to join the Yahoo group to find the files for download.
