An Alternative to the Cook-Levin Theorem
Yes, for example TMSAT (Turing Machine SAT):
TMSAT = $\{ \langle \alpha, x, 1^n, 1^t \rangle : \exists u \in \{0,1\}^n$ such that $M_\alpha$ outputs 1 on input $\langle x,u \rangle$ within $t$ steps. …

Decision problem restricted to inputs that satisfy some necessary condition.
Consider the following decision problem:
Problem 1
INPUT: A graph G.
OUTPUT: YES if G is 3-colorable, NO if not.
This is a well-known NP-complete problem. Now suppose that we have a necessary (but n …

What is the relationship between "translation" and time complexity?
Your question reminded me of matroid problems. With these it is of great importance to specify how the input is given, as translating between input forms can increase the size of the input exponential …
