public class NewcombOperators extends Object
Implementation of the Modified Newcomb Operators.From equations 2.7.3 - (12)(13) of the Danielson paper, those operators are defined as:
4(ρ + σ)Yρ,σn,s =
2(2s - n)Yρ-1,σn,s+1 + (s - n)Yρ-2,σn,s+2
- 2(2s + n)Yρ,σ-1n,s-1 - (s+n)Yρ,σ-2n,s-2
+ 2(2ρ + 2σ + 2 + 3n)Yρ-1,σ-1n,sInitialization is given by : Y0,0n,s = 1
Internally, the Modified Newcomb Operators are stored as an array of
PolynomialFunction
:Yρ,σn,s = Pk0 + Pk1n + ... + Pkjnj
where the Pkj are given by
Pkj = ∑j=0;ρ ajsj
