Detailed Description

template<template< class W >class R>
class graphgen::Ratio< R >

Ratio functor calculates the appropriate weight ratio for a proposed local update.

According to the ensemble the functor is selected from, W(beta)/W(alpha) is calculated, alpha being the pre- and beta the post-update graph configuration.

In order to calculate weight ratios in any situation, there must be an overloaded version of operator() for any reasonable combination of ensemble and weight type. Exploiting this, for example, calculation using logarithmic weights types is possible.

This functor implements the generic weight ratio function, taking only moderately into account the specific restricted graph ensemble. Specialize the template for any shape restriction functor to specifically exploit the properties of restricted ensemble.

Parameters:

R

shape restriction functor class. Generic calculation may not use this
