GA 3.2.4 (2024-01)
GA 3.2.3 (2022-10)
- Fixed warnings in C++ code under CRAN request.
GA 3.2.2 (2021-10)
- Fixed doi in JSS and RJ publication.
GA 3.2.1 (2021-04)
- Forced
elitism argument to be an integer.
- Fixed passing further fitness function arguments in
de().
- Fixed passing suggestions in
gaisl().
- Added an example of
postFitness usage in the vignette.
- Added rmarkdown in the list of suggested package (as required by CRAN).
GA 3.2 (2019-01)
- Added website using pkgdown.
- Added a section to vignette on integer optimisation.
- Added function
de() implementing Differential Evolution based on the description in Simon (2013) Evolutionary Optimization Algorithms.
- Bug fix in C++ code calling
pow() function.
- Bug fix in
gails() when suggestions are provided.
- Long outputs in
summary() function calls are shortened.
- Fix a bug in
gaperm_pbxCrossover().
GA 3.1.1 (2018-05)
- Bug fix in C++ code calling
pow() function.
GA 3.1 (2018-05)
- Genetic operators available in C++ using Rcpp package.
- Add parameter
"useRcpp" in gaControl() to control if the C++ implementation of genetic operators should be used. By default is set to TRUE.
- Renamed input parameters
min and max to lower and upper. The old nomenclature is still accepted but deprecated.
- Added
stopParallel() function to stop a cluster if parallel = TRUE, including registerDoSEQ() to avoid problems if foreach loop is used after.
- A parallel cluster is automatically stopped unless a registered parallel back end is provided as argument to
parallel argument in the ga() or gaisl() function call.
- Bug fix in
gaperm_Population() when min > 1. Thanks to Romero Barata.
- Update âA quick tour of GAâ vignette.
- Add
README.Rmd that is shown in GitHub and CRAN.
- Create a sticker for the GA package.
GA 3.0.2 (2016-06)
- In interactive sessions use different monitor functions depending on whether or not is an RStudio session. This is due to different capabilities of the several consoles from which R can be run.
GA 3.0.1 (2016-05)
- doRNG package moved from Depends to Suggests due to the unavailability of the binary version of the package on Windows. As a consequence, GA package can be installed even without doRNG being installed, but in this case results are not reproducible by setting the seed if GAs are executed in parallel.
GA 3.0 (2016-05)
- Added option to provide a cluster for parallelisation.
- Added GA-hybrid using
optim() for local search.
- Added GA Islands model in
gaisl().
- Rewrite of
gaMonitor() to clear the previous output before printing the info about the current iteration. Old version is available in gaMonitor2(). Same behaviour for gaislMonitor() and gaislMonitor2().
GA 2.3 (2015-07)
- Added documentation vignettes.
GA 2.2 (2014-10)
- Slight modification to
plot.ga() method.
- Included link in main ga documentation to genetic operators.
- Added
ga_pmutation() function to allow GAs having variable mutation probability.
- pdf files (previously included as vignettes) moved to
inst/doc with corresponding index.html.
GA 2.1 (2014-05)
.printShortMatrix() is a function to print part of rows/columns of a matrixprint.summary.ga() accept arguments to be passed to .printShortMatrix(). This allow to shorten the printed output in case of large dimensions for the matrices containing the suggestions and the final solutions.plot.ga() now shadowed the area between the max and the median of fitness values at each iteration. Changed to pch from 17 to 1 for means.- Function
gaSummary() is embedded in the code, so it cannot be defined by the user.
- Added function
ga_pmutation() for computing variable mutation probability.
- Modified main function
ga() to allow for pmutation to be a function. This enables the use of variable mutation rate.
- Export
plot.ga class in NAMESPACE and used as S4 method.
- Computing summaries at each step is done by function
gaSummary(), but it may be defined by the user.
- Export
summary.ga class in NAMESPACE and used as S4 method.
- Default for suggestions argument in
ga() is set to NULL.
- Fixed a bug in
gabin_uCrossover().
- Added description of slots in the help page for
ga-class.
- Bug fix on setting maxfitness.
- Bug fix on passing seed argument when âsnowâ parallel is used.
- Add explicitly stop clusters if parallel is used.
- Parallel computing improving set up of clusters.
GA 2.0 (2013-08)
- Option for parallel computing.
- Added argument keepBest to include the best solution at each iteration.
- Bug fix when using suggestions argument.
GA 1.1 (2013-04)
- Update citation and references to JSS paper.
GA 1.0 (2012-06)
