Full Changelog: v3.1.1...v3.1.2

Paradiseo 3.1.1 — "Janus"

This release mainly fixes a lot of warnings, and adds binary partition support for local searches.

Main features

• Refactor eoForge*: move the instantiate(double) interfaces of eoForgeVector as instantiate_from and adds two separated sets members for instantiation.
• Adds eoForgeMap, same features than an eoForgeVector, but allowing to bind a string name to the instance.
• Potalas fixed eoStandardBitMutation.
• Adds moBinaryPartition & co., which allows to implement local search on, well, binary partitions.
• Adds a new constructor for moSA, without a cooling schedule, but with a continuator.
• Adds eoRealToIntInit.
• Allow readFrom to work on std::cin + invalidTag. This allows to read from any istream.

Minor changes

• General updates to remove warnings with modern compilers.
• Xin Ai found the missing MO tutorial and added it to the documentation.
• Leo Bertheas fixed a bug in edoEstimatiorNormalAdaptive (used to implement CMA-ES).
• Some operators were still using std::cout to print stuff, they are now only using std::clog.
• Use the STL's random generator features wherever possible, instead of old adhoc implementations.
• Thanks to Jxtopher for fixing a bug in eoProportionalSelect.
• Use smart pointers instead of raw ones in eoForge*.
• Guard some languages features deprecated in C++17.

Other good news

• Eremey Valetov used Paradiseo for a paper in physics (see the website).

Paradiseo 3.0.0 — "Epimetheus"

This release mainly adds automated algorithm design capabilities to Paradiseo.

Paradiseo is now requiring a modern compiler handling the C++17 standard (and CMake 3.10).

The main new features are:

• an interface to the IOHexperimenter benchmarking platform (see eoEvalIOH),
• automated operator instantiation and assembling (see classes around eoAlgoFoundry),
• a full example of how this can be used to do automated algorithm selection (of a FastGA over IOH's W-model benchmark) with irace,
• some functions to automatically export irace's configuration files from a Paradiseo code itself,
• eoAlgoRestart: an algorithm that can manage restarts (and automates the necessary state reset),
• Singularity container definition files that scripts how to build Paradiseo.

Since the last release, a lot of small additional features have also been added:

• "fast" bitstring mutation operators (state of the art ones),
• eoEliteSelect: a sequential selector that returns the best individual,
• an accessor to get an eoValueParam by its name,
• eoEvalCmd: an evaluator which calls a system command,
• eoEvalNamedPipe: an evaluator which interacts through named "FIFO" pipes,
• eoEvalNanThrowException: an evaluator which checks for NaN values,
• edoContAdaptiveFinite: a continuator that checks a covariance matrix state.

And the HTML documentation's style is now more beautiful, and one recovered the lost MO tutorials.

Other changes

• fix edoEstimatorNormalAdaptive (used in EDO/CMAES).
• refactor UF_random_generator to fit the new std::shuffle.
• fixed eoSIGContinue under Windows.
• fixed several compilation warnings.
