--- Changelog ---

|
|
|
2.05: Added ScatterSearch (real-valued), BinaryScatterSearch, and the Bayesian Optimization Algorithm (thanks
|
|
to Alexander Seitz) to the base package. Added JobList and some statistical measures. Requires to put
|
|
the JSC package on the class path for Mann-Whitney test.
|
|
|
|
2.046: Adaptions to the MatlabInterface: explicit data types are used now, added integer problem support.
|
|
Additional Integer operators: segment-wise mutation and crossover. Added an abstraction over individual
|
|
initialization methods. Added the ERPStarter class which is an example for running a csv-configured
|
|
optimization. Some bug-fixes and clean-ups.
|
|
|
|
2.045: Added MOOCMAES (de Paly); compatibility with Java 1.5 (Draeger); Revision of the statistics class
|
|
with improved pipelining of data (InterfaceAdditionalPopulationInformer); improved FunctionArea
|
|
concerning history, labels, legend and graph coloring; improved StringSelection; restructured
|
|
Terminators, additional ParetoMetricTerminator. Further bugfixes and clean-ups.
|
|
|
|
2.043: Added proper Population equality predicate.
|
|
|
|
2.042: Some bugfixes. Removing dependency on sun.beans.editors, replaced non-free jpeg-codec. There should
|
|
be no more problems on OpenJDK. Added a simple initialization range, especially for use from Matlab.
|
|
Some restructurings (RNG and Mathematics is now in eva2.tools.math). Some cleanup.
|
|
|
|
2.040: Several updates: The clustering interface has been changed for easier implementation of adaptive clustering
|
|
methods. The GradientDescentAlgorithm has been updated and some benchmark problems been made derivable.
|
|
The ClusterBasedNiching algorithm has been slightly restructured updated according to the new clustering.
|
|
An additional clustering method is included: nearest-best clustering with dynamic adaption of niche radius.
|
|
Some changes to (text) statistics: they are now printed regarding the full solution set instead of the
|
|
last population. The Population field "size" is now termed "targetSize" to avoid misunderstandigs. Populations
|
|
can be initialized using a Random Latin Hypercube sampling. Some basic console options are recognized:
|
|
EvA2 can be started without splash screen and even without GUI. If configuration file is given which was
|
|
earlier saved from the GUI, the thus defined optimization run is then processed automatically by EvA2.
|
|
|
|
2.036: New graph selection mode for statistic plots: every property may be selected independently.
|
|
A simple plot legend is produced in the graph window, which can be deactivated.
|
|
|
|
2.035: Reactivated some of the model-based functionality within the GO framework. Minor bugfixes.
|
|
|
|
2.034: Adding a generic parameter control method for optimizers, currently used by PSO to adapt inertness depending
|
|
on EvaluationTerminator or GenerationTerminator instances defining the number of function evaluations.
|
|
The new package is eva2.server.go.operators.paramcontrol.
|
|
A Population may now be ordered by a specific fitness criterion, employed, e.g., by Nelder-Mead-Simplex.
|
|
|
|
2.033: There was an interesting problem with the Matlab-Interface, which just hung up after extensive optimization
|
|
loops, yet only if Matlab was started without X-forwarding (which is necessary for qsub, e.g.).
|
|
Debugging was tedious, since the debugging using System.out. itself caused threading deadlocks. The
|
|
problem showed up to be with System.out itself. Whatever Matlab does with that stream, it does it differently
|
|
depending on the X-forwarding option. More specifically, the text written to System.out when X-forwarding
|
|
is not available seems to never show up (as opposed to being printed to the console when X-forwarding is on)
|
|
and silently fill up the JVM-memory. I havent the faintest idea why there havnt been OutOfMemory exceptions
|
|
earlier or whether and how the deadlocks have to do with it.
|
|
The ingenious solution was: dont print anything to System.out, which is now done at verbosity 0.
|
|
|
|
2.032: Some cosmetics, e.g. to AbstractEAIndividualComparator and older MOCCO classes.
|
|
|
|
2.031: Some updates to the OptimizerFactory. Review of the MatlabInterface with adding an own options structure.
|
|
Better access to the EvAClient, which now may have a RemoteStateListener added monitoring the optimization run.
|
|
|
|
2.030: Added an EnumEditor to access enums easily through the GUI, which will replace SelectedTags sometimes.
|
|
IPOP-ES and RankMuCMA mutator have been added lately (wow!).
|
|
Cleaned up the IndividualInterface and reduced the usage of InterfaceESIndividual. This
|
|
means that, e.g., that DE and PSO now also work on GAIndividualDoubleData. Because this
|
|
requires much time for transcoding, however, this is not useful by itself. Yet it could be
|
|
interesting for combined individuals composed of two data types.
|
|
Cleaned up MutateXXDefault to a single MutateDefault, too. DE may now do range checking.
|
|
The "Description" button has made space for a "Show Solution" button. The Rank-Mu-CMA was improved
|
|
to use a CMAParameterSet which is associated with populations and not static any more.
|
|
Included Nelder-Mead-Simplex and CMA-ES as post processing methods.
|
|
|
|
2.029: Tuned the 2d-graphs which now paints quicker and changes size depending on the
|
|
surrounding plot window. Added a preloader-thread to accelerate the GUI at starting time.
|
|
|
|
2.028: Tuned the Population to sort only when necessary on calls to getBestN... Added StatisticsDummy.
|
|
Slightly tuned SimpleProblemWrapper to call initProblem of simple problems if available.
|
|
|
|
2.027: Renamed SetData and SetDataLamarckian from individual data type interfaces to SetGenotype and SetPhenotype.
|
|
Repaired the GenericArrayEditor. Population measures can now be plotted in stats.
|
|
|
|
2.026: Added DiversityTerminator and KnownOptimaTerminator, slightly changed InterfaceTerminator for these
|
|
and InterfaceStatistics to provide termination message to text window.
|
|
Killed redundant method getGenerations() in Population. Population.getAllSolutions now returns a
|
|
SolutionSet combining last population with a set of possibly archived solutions.
|
|
Post processing with HC may now use variable step size mutation.
|
|
|
|
2.025: FunctionArea may now plot circles easily. The FLensProblemViewer seems to be cured.
|
|
|
|
2.024: Cleaned up AbstractGOParams, deactivated parent logging (saving memory)
|
|
|
|
2.023: Cleaned up the PF strategy
|
|
|
|
2.022: Some changes to the SimpleProblemWrapper, not of great interest. However, simple problems may now access a plot
|
|
quite easily.
