Functions
GIRGS_API std::vector< double >	girgs::generateWeights (int n, double ple, int weightSeed, bool parallel=true)
	The weights are sampled according to a power law distribution between [1, n) More...
GIRGS_API std::vector< std::vector< double > >	girgs::generatePositions (int n, int dimension, int positionSeed, bool parallel=true)
	Samples d dimensional coordinates for n points on a torus \([0,1)^d\). More...
GIRGS_API double	girgs::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 search over an estimation function. More...
GIRGS_API std::vector< std::pair< int, int > >	girgs::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 probability \( \left(\frac{w_u w_v / W}{|| x_u - x_v ||^d}\right)^\alpha \) or 1.0 if the term exceeds 1.0. More...
GIRGS_API void	girgs::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 position attribute for each Node. More...
