Detailed Description

simple random number generator, used in ensemble classes

integer pool

Todo:

offer different RNGs for use and remove it

represents a set of integers in [0,m-1]. Class is parametrised by an integer type. Elements can be taken from and put back into the pool. Two subsets are identified: taken and available elements can be

Function Documentation

unsigned int graphgen::ltm_index	(	unsigned int	i,
		unsigned int	j
	)			[inline]

calculate storage index of a_{ij} in a lower triangular matrix for storage of symmetric matrices

this is used in weight storage tables (half memory usage), and for correlation histograms

Todo:

use symmetric_matrix instead
