Deciding Irreducibility/Indecomposability of Feedback Shift Registers Is NP-Hard
Feedback shift registers (FSRs) are used as a fundamental component in electronics and confidential communication. A FSR f is said to be reducible if all the output sequences of another FSR g can also be generated by f and the FSR g costs less memory than f. A FSR is said to be decomposable if it ha...
