girgs::generateWeights
GIRGS_API std::vector< double > generateWeights(int n, double ple, int weightSeed, bool parallel=true)
The weights are sampled according to a power law distribution between [1, n)

girgs::generatePositions
GIRGS_API std::vector< std::vector< double > > generatePositions(int n, int dimension, int positionSeed, bool parallel=true)
Samples d dimensional coordinates for n points on a torus .

girgs::generateEdges
GIRGS_API std::vector< std::pair< int, int > > generateEdges(const std::vector< double > &weights, const std::vector< std::vector< double >> &positions, double alpha, int samplingSeed)
Samples edges according to weights and positions. An edge between node u and v is formed with probabi...

girgs::scaleWeights
GIRGS_API double scaleWeights(std::vector< double > &weights, double desiredAvgDegree, int dimension, double alpha)
Scales all weights so that the expected average degree equals desiredAvgDegree. Implemented as binary...

girgs::saveDot
GIRGS_API void saveDot(const std::vector< double > &weights, const std::vector< std::vector< double >> &positions, const std::vector< std::pair< int, int >> &graph, const std::string &file)
Saves the graph in .dot format (graphviz). The weight is saved as a label and the coordinates as a po...
