oj! Algorithms
2013-04-16: Released v34
10 years have passed since ojAlgo was registered at SourceForge, and its history dates back further than that. According to ohloh the ojAlgo code base represents an estimated effort of 16 person-years (and they're actually missing a couple auxiliary/minor modules).

ojAlgo change log for the last 10 releases
Just before releasing v32 the Java Matrix Benchmark was executed to compare ojAlgo performance to other linear algebra packages. v32 and v33 should be equivalent in terms of linear algebra functionality and performance. v34 contain changes to how multi-threading is implemented that could impact (improve) performance. Hope to run the tests again soon.

ojAlgo is Open Source Java code that has to do with mathematics, linear algebra and optimisation. ojAlgo really is 100% pure Java source code. There are no calls to native (C or Fortran) libraries. In fact there are no dependencies at all. Nothing besides a Java SDK is needed to compile or execute the code. Its feature set make it particularily suitable for use within the financial domain.
