ecr 2.2.1

Fixes

• Fixed warnings raised by r-devel versions
• Fixed typo in the docs of approximateRefSets yielding the function not being exported

ecr 2.2.0

Fixes

• Fixed bug in mutPolynomial where parameter lower was sanity-checked twice and upper not at all
• Fixed some typos in function documentations
• Fixed bug in updateParetoArchive: optimization direction, e.g., minimize first, maximize second objective are now respected

Added

• More literature references in documentation

New features

• Performance assessment for stochastic multi-objective optimization algorithms (very powerful tool)
  • Flexible scatterplots in 2D and 3D
  • Function to calculate a set of unary and binary performance indicators for a set of problems and algorithms
  • Function to visualize indicator distrbutions
  • Functions to perform statistical tests and output results as well-formatted LaTeX tables
• Exported helper functions getNumberOfChildren, getNumberOfParentsNeededForMating and generatesMultipleChildren

ecr 2.1.1

Fixes

• Fixed: bug in replaceMuCommaLambda if n.elite was not set by hand
• Fixed: selGreedy throws error if n.select is larger than the number of individuals passed (this led to hard-to-detect errors in (mu, lambda) strategies and white-box approach)

New Features

• Added terminator stopOnMaxTime

ecr 2.1.0

New Features

• uniform crossover recombinator recUnifCrossover
• parameter log.stats for ecr function (possibility to define fitness statistics to be logged)
• logical log.pop argument for ecr function (should each population be saved in the logger?)
• possibility to store additional stuff in logger via ‘extras’
• terminators stopOnEvals and stopOnOptY

ecr 2.0.0

• First submission of ecr 2 to CRAN.
• Almost everything changed.

These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
