cecpy 0.1.5

Python bindings for an implementation of CECs benchmarks in C++23

cecxx

Implementation of IEEE Congress of Evolutionary (CEC) Bound-constrained Single Objective Numerical Optimization benchmarks in C++23 with available interface bindings to Python and R.

About

The {cecxx} is a novel implementation of IEEE CEC BC-SOP benchmarks in C++23, which compared to the official implementation does not:

• leak memory
• involve multiple IO operations during each objective function call.

Solving the above problems results in reliable and fast implementation that is ready to be used in your numerical experiments.

Check the examples directory to see how to use this library.

The {cecxx} includes also free-standing implementations of objective functions utlized by CEC benchmarks, see include/cecxx/functions for details.

[!NOTE] This is not official implementation of CEC BC-SOP benchmarks. However, it can be used as a drop-in replacement. The {cecxx} is extensively tested to be compliant with the official implementations by employing property-based testing. See test/compliance for details.

Installation

To install the {cecxx} with cmake, run below commads:

git clone https://codeberg.org/ewarchul/cecxx.git
cd cecxx
cmake \
  -B build \
  -S . \
  -D CMAKE_CXX_STANDARD=23 \
  -D CECXX_BENCHMARK_DATA_STORAGE_INSTALL_DIR="${HOME}/.local/state/cecxx"
cmake --build build
cmake --install build

If you are using just then you can run:

just install_cxx

to build and install the library. See Justfile for details or inspect CMakeLists.txt for all available options.

[!NOTE] {cecxx} is a passive project. It means, that you have to specify the project configuration. See CMakePresets.json for defined workflows.
