Moe is a C++14 header-only dependency-free library providing generic implementations of some metaheuristic algorithms

The main goal of Moe is to provide a generic and easy way to implement fast solving systems from any complexity with C++.

Moe stands for Maybe Overpowered Entity, but isn't limited to it.

Moe gives a way for the user to completely define the behavior of algorithms, all parameters are adjustable, and the structure allows to easily add features or custom Mutations/Crossover/Algorithms.

Take a look at a base sample using Moe (examples/square_root.cpp):

This example illustrates how Differential Evolution can be used to search for the square root of a number (in this case 2261953600), the known answer is 47560.

#include <moe/moe.hpp>
#include <iostream>
#include <string>

int main()
{
    DifferentialEvolution<int> moether(20);

    long long n = 2261953600;

    moether.setFitnessFunction( [n](auto moe) -> double
    {
        long long genotype = moe.genotype[0];
                
        double error = std::abs(n - genotype*genotype);

        return 1/(error+1);
    });

    moether.run( 50 );  // run 50 generations

    long long genotype = moether.getBestMoe().genotype[0];

    std::cout   << "genotype: "     << genotype << "\n"
                << "fitness: "      << moether.getBestMoe().fitness << std::endl;
}

Compiling:

The following clone Moe and generates with CMake

git clone https://github.com/tonykero/Moe.git
cd Moe
mkdir build && cd build && cmake ..

then under linux

make

or

cmake --build .

or (if with MSVC, and -DDEBUG=1 was not specified)

cmake --build . --config Release
