Polynomial time mapping reduction

WebIn this paper, we investigate how to compute the throughput of probabilistic and replicated streaming applications. We are given (i) a streaming application whose dependence graph is a linear chain; (ii) a one-to-many mapping of the application onto a fully heterogeneous target, where a processor is assigned at most one application stage, but where a stage … WebHere is how we can reduce x to an instance y of B, in polynomial time: Solve x. We can do this in polynomial time since A is in P. We get an answer, either YES or NO. If the answer in step 1 is YES: compute a YES instance of language B and return it as y. If the answer in step 1 is NO: (You know what to do). Either of steps 2 and 3 can also be ...

WebAn emerging solution for modelling late-reflections is “Surface-Based” Geometrical Acoustics. These formulations map a distribution of rays arriving at a boundary onto a pre- defined ‘approximation space’ of basis functions spanning position and angle, so the sound field is represented by a vector of boundary coefficients.

The reduction takes an arbi-trary SAT instance ˚as input, and transforms it to a 3SAT instance ˚0, such that satisfiabil- ity is preserved, i.e., ˚0 is satisfiable if and only if ˚is satisfiable. Recall that a SAT instance

WebPolynomial reduction: L 1 P L 2 means that there is a polynomial time computable func-tion f such that x 2L 1 if and only if f(x) 2L 2. A more intuitive way to think about this is that if we had a subroutine to solve L 2 in polynomial time, then we could use it to solve L 1 in polynomial time. Polynomial reductions are transitive, that is, L 1 ...
