Optimatika

We build mathematical optimization tools for Java developers.

ojAlgo

ojAlgo is our open source library for the JVM: LP, QP and MIP solvers and fast linear algebra, in pure Java with zero dependencies. MIT licensed, in development since 2003. Start with the Optimisation Cookbook.

For AI coding assistants

ojAlgo-skills teaches Claude, Codex and other assistants to write correct ojAlgo code: optimisation models, linear algebra and portfolio optimisation. Listed in Claude's plugin directory as ojAlgo.

Optimisation Service

When a model needs more than the built-in solvers, run the same model on HiGHS, SCIP and Clarabel. The Optimisation Service is a container you deploy in your own cloud or cluster; your Java code talks to it through a small client with no native code. Learn more.

Support

Priority support and consulting for teams building on ojAlgo, through one subscription. Nobody knows the library better – we wrote it.
