Constructor & Destructor Documentation

template<template< class D > class C, class D>

Bial::MaxSumPathFunction< C, D >::MaxSumPathFunction	(	const C< D > &	new_intensity,
		const C< D > &	handicap,
		double	new_alpha = `0.0`,
		double	new_beta = `0.5`
	)

Basic constructor.

Date: 2015/Jun/24

Parameters
