java mixed integer linear programming (MILP) solver library that reads MathProg

[Jorge Garcia de Alba]

Good day!

A java mixed integer linear programming (MILP) solver library that
reads MathProg would be wonderful. If there is no such thing, it
should exist.

Identifying binding constraints

[Jorge Garcia de Alba]

Hello,

I use org.apache.commons.math3.optim.linear package. How would one go
about identifying binding constraints? It would be great to have a
method that tells one which constraints are binding.

Have a great day.

distribution fitting with commons math

[Jorge Garcia de Alba]

Hello,

I would like to use commons math to fit a probability distribution to
my data and then test for close fit using the kolmogorov-smirnov test.
Where can I find example code on how to do this? Have a great day.

Re: SimplexSolver - Candidate Solutions and PointValuePairs

[Jorge Garcia de Alba]

Hello,

I was hoping I could look at all solutions (non-optimal and optimal)
found by algorithm to see if there anything useful there. It is my
understanding that once a feasible solution is found, algorithm then
just refines the feasible solution to a optimum feasible solution. I
am currently using a brute-force approach to find those optimal
solutions and it is working. Thanks.

Hello,

How can I get a PointValuePair for each candidate solution when using
SimplexSolver?

Have a great day.

Re: Using Apache Commons Math in Java Language Routines (SQL/JRT) in HSQLDB

[Jorge Garcia de Alba]

Hello,

Would apache commons math be interested in adding code that could
easily be used in java language routines or is this out of scope? I
think they would be the best choice for implementing this.

This is how I imagine it would be used.
https://github.com/xjrga/linearprogramming

Here is information on java language routines.
http://hsqldb.org/doc/guide/sqlroutines-chapt.html#src_jrt_routines

Thanks.

Using Apache Commons Math in Java Language Routines (SQL/JRT) in HSQLDB

[Jorge Garcia de Alba]

Hello,

I am interested in using the simplexsolver in a java language routine
in hsqldb. Hsqldb requires that the body of the java language routine
to be a static method. I wonder if such methods could be created and
implemented so they could be easily be used in java language routines.
Great job.
