- Update to v55.1.0
* Added
~ org.ojalgo.data
+ New package org.ojalgo.data.cluster with k-means and greedy
clustering algorithms implemented, as well as
generalisations, specialisations and combinations of those.
+ DataProcessors now has a method Transformation2D
newRowsTransformer(Function<SampleSet, UnaryFunction>) to
complement the existing newColumnsTransformer.
~ org.ojalgo.random
+ SampleSet gained a couple of methods; getMidrange() and
getRange().
* Changed
~ org.ojalgo.array
+ Sorting is no longer parallel/multi-threaded. The previous
implementations made use of the common ForkJoinPool.
~ org.ojalgo.data
+ Creating a JMX bean (to monitor throughput) with BatchNode
is now optional, and the default is to not create them.
(Used to always create them.)
~ org.ojalgo.netio
+ The FromFileReader and ToFileWriter interfaces and their
implementations used to extend and delegate to code in the
org.ojalgo.type.function package. Much of what was in that
package has been moved to and merged with stuff in the
org.ojalgo.netio package.
+ The FromFileReader.Builder and ToFileWriter.Builder
builders now use generic "file" types. They used to be
implemented in terms of Java's File, but can now be
anything like Path or ojAlgo's own SegmentedFile,
ShardedFile or InMemoryFile.
+ The DataInterpreter gained some additional standard
interpreters, as well as utilities to convert back and
forth between byte[].
~ org.ojalgo.random
+ SamleSet no longer makes use of parallel/multi-threaded
sorting – to avoid making use of the common ForkJoinPool.
~ org.ojalgo.type
+ The AutoSupplier and AutoConsumer interfaces are removed.
They used to provide abstract/generalised functionality for
FromFileReader and ToFileWriter in the org.ojalgo.netio
package. All features and functionality still exists, but
in terms of the more specific/concrete FromFileReader and
ToFileWriter. If you directly referenced any of the various
utility methods in AutoSupplier or AutoConsumer they're now
gone. They primarily existed so that FromFileReader and
ToFileWriter could access them (from another package). The
features and functionality they provided are now available
through other classes in the org.ojalgo.netio package –
like FromFileReader.Builder and ToFileWriter.Builder.
* Fixed
~ org.ojalgo.data
+ In DataProcessors, the CENTER_AND_SCALE transformation
didn't do exactly what the documentation said it. That's
been fixed.
- Update to v55.0.2
* Added
~ org.ojalgo.type
+ A new cache implementation named ForgetfulMap. To save you
adding a dependency on Caffeine or similar.
~ org.ojalgo.optimisation
+ There is a new OptimisationService implementation with
which you can queue up optimisation problems to have them
solved. This service is (will be) configurable regarding
how many problems to work on concurrently, and how many
threads the solvers can use, among other things.
* Changed
~ org.ojalgo.optimisation
+ Refactoring and additions to what's in the
org.ojalgo.optimisation.service package. They're breaking
changes, but most likely no one outside Optimatika used
this.
+ Minor internal changes to how the IntegerSolver works.
There's now an equal number of worker threads per
worker-strategy.
* Deprecated
~ org.ojalgo.type
+ TypeCache is replaced by ForgetfulMap.ValueCache.
- Update to v55.0.1
* Added
~ org.ojalgo.concurrent
+ Addition to ProcessingService that simplify concurrently
taking items from a BlockingQueue.
* Changed
~ org.ojalgo.random
+ Refactored SampleSet (internally) to be better aligned with
recent changes to other parts of the library. Primarily the
class now uses int indices for all internal calculations.
Also added a new java.util.stream.Collector implementation
to simplify SampleSet creation from streams.
* Fixed
~ org.ojalgo.optimisation
+ Fixed a bug where the (new) LP solver would fail to
recognise unbounded problems and instead return a solution
with infinite values, stating it to be optimal.
