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

Here's a blog post outlining what to do:

ojAlgo v55.1.0 is out!

Changes with this minor release:
1. New clustering support
2. Major refactoring of all (file) reader/writer utilities

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.

@engineers_feed Got an hp calculator as an engineering student. Getting used to RPN was no problem. Since then I'm very slow at using "normal" calculators. I (still) really have to think about in which order I should press the keys. Luckily the Calculator app on my Mac has RPN mode.

@delabassee So, what did he say?

@optimatika spends 4300% more time coding than tweeting (if you wonder why I don't tweet that much)

@shipilev Try a not-so-smart charger. Same thing happened to me. I managed to charge the battery by first pushing in a base charge with an older "dumb" charger, and later switching to the newer smart charger.

@thomaswue @graalvm Why 3?

@gunnarmorling In eclipse there is a "Clean Up" and/or "Save Action" that will replace all specified variable types with 'var'. How stupid is that!? (The opposite would make more sense.)

Just released ojAlgo v53.2.0.

ojAlgo now (finally) includes an FFT implementation, and an effort has been made to assert it really is fast – as fast as can be in pure Java.

Also blogged about how to use 2D DFT for image processing with ojAlgo.

@PMinborg Wouldn't it be better to just not use "var" in these cases?

That's an animated png file, but you only see the first frame here at Twitter.
