I am a full-time consultant and provide services related to the design, implementation and deployment of mathematical programming, optimization and data-science applications. I also teach courses and workshops. Usually I cannot blog about projects I am doing, but there are many technical notes I'd like to share. Not in the least so I have an easy way to search and find them again myself. You can reach me at firstname.lastname@example.org.
OMPR (Optimization Modelling Package in R) is a DSL to model and solve Mixed Integer Linear Programs. It is inspired by the excellent Jump project in Julia.
Here are some problems you could solve with this package:
What is the cost minimal way to visit a set of clients and return home afterwards?
What is the optimal conference time table subject to certain constraints (e.g. availability of a projector)?
If you run a radio station :) What is the optimal way to play music such that your users do not have to listen to the same songs too often?
TheWikipediaarticle gives a good starting point if you would like to learn more about the topic.
This is a beta version. Currently working towards a first stable version for CRAN. At the moment not recommended for production systems / important analyses. Although most obvious bugs should be gone. Happy to get bug reports or feedback.
