First published in October 2021, then updated in February 2022. ojAlgo contains pure Java LP, QP and MIP solvers. That's something very unique. There are very few pure Java alternatives…
Browsing through code that uses ojAlgo it's quite common to see it being used inefficiently or at least not the intended way. Here's an example code line, seen in the…
Almost everything in ojAlgo makes use of or interacts with some array based data structure. To always code directly against raw arrays like double[], float[] or Number[] would be awkward.…
This is an updated version of a post from when artificial neural networks (with ojAlgo) were first introduced. Since then new features have been added, the API changed a bit,…
ojAlgo's MatrixStore interface largely defines what you can do with matrices. There are many implementations of that interface provided. They store the elements differently and exploit structure to perform operations…
v48.3.0 had a pure Neural Network focus: Support for floatPossibility to "get" all individual parameters of the networkNew file format to save trained networks to diskImproved separation between building, training and…
With version 19.3 (released 2019-11-19) GraalVM supports Java 11. This benchmark compares the Community Edition (CE) with the Enterprise Edition (EE) and compares them both to a the usual HotSpot…
This version primarily brings changes to the ojAlgo type system. ojAlgo is all about numbers and contains a lot of generic classes and interfaces to deal with various types of…
