Does the apply to representation of complex numbers, which is not uncountably infinite and represented by floats?
Yes. It applies to "linear algorithms", which are basically functions of the form
fun f(x1, x2, x3, ...): t1 = 3*x1 + 2*x2 t2 = 4*t1 + 5*x3 ... return (some subset of t vars)
The cost model is just the number of additions performed.
Yes. It applies to "linear algorithms", which are basically functions of the form
where each ti is a linear combination of previous t vars, inputs x vars, or constants.The cost model is just the number of additions performed.
