- 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.

- Update to v55.0.0
* Changed
~ org.ojalgo.function
+ The BigDecimal valued constants in BigMath for E, PI and
GOLDEN_RATIO are redefined with more decimal digits.
+ The BigDecimal valued functions in BigMath for EXP, LOG,
SIN and COS are re-implemented to produce much more
accurate results.
~ org.ojalgo.optimisation
+ The new LP solver implementation is now the default
alternative.
+ The two classes LinearSolver.GeneralBuilder and
LinearSolver.StandardBuilder are replaced by a common
LinearSolver.Builder. Consequently the methods
newGeneralBuilder() and newStandardBuilder() are deprecated
and replaced by newBuilder().
~ org.ojalgo.scalar
+ Re-implemented Quadruple's divide method using primitives
only. (Previously delegated to BigDecimal.)
* Deprecated
~ org.ojalgo.data
+ Everything related to downloading (historical) financial
data is deprecated. It's already broken (due to changes in
the external "service") and we're not going to try fix it.
* Removed
~ org.ojalgo.structure
+ Removed a bunch of stuff that was deprecated in Factory1D,
Factory2D and FactoryAnyD and/or some of their
sub-interfaces.

- Update to v54.0.0
* Added
~ org.ojalgo.matrix
+ Added the ability to specify the initial capacity of a
SparseStore.
+ More efficient sparse to sparse copying of SparseStore.
+ New option to use a builder when initially setting the
elements of a SparseStore.
+ When setting (or adding to) elements there used to be
internally synchronized code. This is no longer the case.
Instead you must call synchronised() to get a synchronized
mutating wrapper. This should make common single threaded
usage faster.
+ The sparse BasicMatrix builder no longer has all the
methods that really only made sense with dense
implementation. The sparse builder implementation changed
to use that new SparseStore.Builder.
~ org.ojalgo.structure
+ There are new methods fillCompatile(...),
modifyCompatile(...) and onCompatile(...) to complement the
already existing "fill", "modify" and "on" methods.
(Inspired by MATLAB's concept of compatible array sizes for
binary operation.)
+ The factory interfaces got methods to construct instances
of compatible sizes/shapes. (Inspired by MATLAB's concept
of compatible array sizes for binary operation.)
* Changed
~ org.ojalgo.matrix
+ The classes Primitive64Store and Primitive32Store have been
renamed R064Store and R032Store. These classes are central
to ojAlgo. The effect of this name change is widespread.
ojAlgo has been transitioning to a new naming scheme over
several versions now, but these classes were left untouched
so far (in part because of how central they are). Now, to
complete the work, it's done! No deprecations, just did it.
Apart from the name change the classes are identical.
+ Vector space method like "add" and "subtract" have been
redefined to no longer throw exceptions if dimensions are
not equal, but instead broadcast/repeat rows or columns.
(Inspired by MATLAB's concept of compatible array sizes for
binary operation.)
~ org.ojalgo.optimisation
+ Refactored, cleaned up deprecations, primarily regarding
how model variables are created. They can no longer be
instantiated independent of a model. You have to first
create the model, and then use that as the variable (and
expression) factory.
~ org.ojalgo.structure
+ Refactored the builder/factory interfaces to better support
creating immutable 1D, 2D or AnyD structures. This has
implications for most ojAlgo data structures. There are
deprecations in all factory classes, but everything that
worked before still works (I believe).
+ The Structure*D, Access*D, Mutate*D and Factory*D
interfaces have all been refactored to make working with
int indices (rather than long) the primary alternative.
Huge data structures, that require long indices, are still
suported – no change in this regard. In reality only a few
implementations actually allowed to create such large
instances. This change is to allow all the other classes to
be implemented using int and not bother (so much) with
long. Users of the various classes in ojAlgo should see no
difference. If you have created your own classes
implementing some of ojAlgo's interfaces you will probably
need to implement some additional methods in those classes.

- Update to v53.3.0
* Added
~ org.ojalgo.function
+ Some additional PowerOf2 utilities.
~ org.ojalgo.netio
+ SegmentedFile that divides a large file in segments to
enable reading those in parallel using memory mapped files
(memory mapped file segments).
~ org.ojalgo.type
+ New primitive number parsers in NumberDefinition. They take
CharSequence rather than String as input and do not create
any intermediate objects. In particular the parseDouble
performs much better than its counterpart in Double. The
downside is that it only handles a limited plain format.
* Changed
~ org.ojalgo.concurrent
+ The reduce(...) methods of ProcessingService are renamed
(deprecated) reduceMergeable(...). In addition there are
now also reduceCombineable(...).
~ org.ojalgo.data
+ The processMapped(...) method of BatchNode is renamed
(deprecated) processMergeable(...). In addition there is
now also processCombineable(...).
+ The reduceMapped(...) method of BatchNode is renamed
(deprecated) reduceByMerging(...). In addition there is now
also reduceByCombining(...).
~ org.ojalgo.type
+ The merge(Object) method of TwoStepMapper has been removed.
Instead there are two new sub-interfaces
TwoStepMapper.Mergeable and TwoStepMapper.Combineable.
- Update to v53.2.0
* Added
~ org.ojalgo.data
+ There is a new package org.ojalgo.data.transform that (so
far) contain implementations of the ZTransform and the
DiscreteFourierTransform. Most notably ojAlgo now contains
an implementation of the FFT algorithm.
+ ImageData has been extended with features to work with
Fourier transforms of images, as well as a Gaussian blur
function.
~ org.ojalgo.function
+ The PolynomialFunction interface now extends
org.ojalgo.algebra.Ring which means it is now possible to
add and multiply polynomials. There’s also been some
refactoring of the internals of the polynomial
implementations.
+ Two new PrimitiveFunction.Unary implementations
PeriodicFunction and FourierSeries. It is now possible to
take any (periodic) function and, via FFT, get a Fourier
series approximation of it (1 method call).
~ org.ojalgo.scalar
+ Some minor additions to ComplexNumber. It is now possible
to do complex number multiplication without creating new
instances (calculate the real and imaginary parts
separately). Added utilities to get the unit roots.
- Update to v53.1.1
* Added
~ org.ojalgo.data
+ New ImageData class that wraps a
java.awt.image.BufferedImage and implements MatrixStore.
Further it adds a few utility methods to simplify working
with image data - convert to grey scale, re-sample (change
size), separate the colour channels…
~ org.ojalgo.matrix
+ It is now possible to create a matrix decomposition
instance and calculate the decomposition with 1 method
call. Previously you had to first call make on the factory
instance and then decompose on the decomposition instance.
Now it is possible to call decomposed directly on the
factory instance.
+ The SingularValue interface now defines a method to
reconstruct a matrix using a specified number of singular
values.
- Initial packaging with v52.0.1
