NTR_KZFD quadratization dispatch not being called

[pedroripper]

This function should verify if the coefficient for each term is negative, so it can call the NTR_KZFD dispatch.

ToQUBO.jl/src/lib/pbo/quadratization.jl

Lines 132 to 148 in 0a7b10b

	function quadratize!(
	aux::Function,
	f::PBF{S,T},
	quad::Quadratization{TERM_BY_TERM},
	) where {S,T}
	# Collect Terms
	Ω = collect(f)
	# Stable Quadratization
	quad.stable && sort!(Ω; by = first, lt = varlt)
	for (ω, c) in Ω
	quadratize!(aux, f, ω, c, Quadratization{PTR_BG}(quad.stable))
	end
	return nothing
	end

We can just follow the same logic from this dispatch:

ToQUBO.jl/src/lib/pbo/quadratization.jl

Lines 116 to 130 in 0a7b10b

	function quadratize!(
	aux::Function,
	f::PBF{S,T},
	ω::Set{S},
	c::T,
	quad::Quadratization{TERM_BY_TERM},
	) where {S,T}
	if c < zero(T)
	quadratize!(aux, f, ω, c, Quadratization{NTR_KZFD}(quad.stable))
	else
	quadratize!(aux, f, ω, c, Quadratization{PTR_BG}(quad.stable))
	end
	return nothing
	end
