comment Why is integer programming in fixed dimension easier than in general?
Is this the case for integer programming without fixed dimension?

comment Is a left invertible element of a ring necessarily right invertible?
You bet me to the finish line... Basically just the fact that left-inverse and right-inverse are not the same thing. Also all this square summable stuff is a red herring. You can take $\mathbb{Z}^\mathbb{N}$.

comment Primary decomposition of ideals
@YACP The restriction to monomial ideals is not necessary. There are algorithms that compute primary decompositions of ideals in polynomial rings.

comment General question on parameter functions
I don't see $\gamma'(t) \neq 0$ as such a central condition. Do you mean that the derivative should exist?

comment Does the statement “There is an algorithm that solves …” make sense?
This is a great answer, thanks. I understood two things now: 1) It's about quantifiers: "There exists an algorithm such that for all instances ..." 2) Any problem with only finitely many instances is 'vulnerable' to the "print the solution" algorithm. (In the Turing machine model with finitely many states)
