We studyq-SATin the multistage model, focusing on the linear-time solvable 2-SAT. Herein, given a sequence ofq-CNF formulas and a non-negative integerd, the question is whether there is a sequence of satisfying truth assignments such that for every two consecutive truth assignments, the number of variables whose values changed is at mostd. We prove thatMultistage 2-SATis-hard even in quite restricted cases. Moreover, we present parameterized algorithms (including kernelization) forMultistage 2-SATand prove them to be asymptotically optimal.
