In general, an Engel expansion with constant terms is a geometric series.
A term with no letters in it is called a "constant term".
However, the largest part comes from so-called dark energy, which accounts for the cosmological constant term.
This square differs from the original quadratic only in the value of the constant term.
Here is a type, and and are constant terms.
If y w then P has constant term 1.
Consequently, we only have to change the objective function of P1 * to (omitting constant terms).
This is an arbitrary choice, but it does influence the complexity up to some constant additive term.
Hence in line 3 we can absorb it into the constant term at the end.
Each class comprises all those polynomials with a particular constant term.
