LP & QP Java Performance Report
ojAlgo aims to have the best set of pure Java solvers available, and to be roughly on par with good native code solvers when the models are not too big or numerically challenging. Below are the result...

I guess this means no preview/incubator until Java 27 at the earliest.

Will it preview in Java 26?

Is "enforced during build" really a good idea? I'm not comfortable with that. It should be during editing, or at save. I'm happy to use a tool to help keep things consistent, but after I say I'm done no tool should change anything in the source code.

The concept of the people's home "the public home" has come to be associated with the Swedish Social Democratic Labor Party and Per Albin Hansson, who launched it as a concept on January 18, 1928, meaning a society that is a home for all the people, and is characterized by consensus and equality.

This is Marco Rubio explaining how the USA promised to defend Ukraine forever if they got rid of their nuclear arsenal left after the Soviet Union fell.
This is why lil marco was sinking into the couch. He was hoping we wouldnât find itâĤso donât RT right now this very second.

Ever wonder how to hook up your mathematical optimisation solver to ojAlgo?

Hooking Your Solver to ojAlgo
This post aims to demonstrate how to make a solver usable from ExpressionsBasedModel. To do that we first implement a very simple solver, and then the integration. There are some very high-level ojAlg...

Released a bug fix for ojAlgo, v55.0.1
In some odd cases the LP solver failed to recognise a problem as unbounded and instead returned a solution with infinite values and stated it to be optimal.

ojAlgo is a pure Java, no dependencies, maths and optimisation library (that's like AI).
Among other things it contains LP, QP and MIP optimisation solvers.
