WebbHere we need the concept of reduction because when you can't produce an output of the problem according to the given input then in case you have to use an emphasis on the concept of reduction in which you can convert one problem into another problem. Note1:- If you satisfy both points then your problem comes into the category of NP-complete class WebbThis chapter introduces the concept of a polynomial time reduction which is a central object in computational complexity and this book in particular. A polynomial-time reduction is a way to reduce the task of solving one problem to another. The way we use reductions in complexity is to argue that if the first problem is hard to solve efficiently, then the …

Be careful, you probably mean a reduction from a problem to another, and not a reduction from an algorithm to another. When a problem A is polynomial time reducible to a problem B, it means that given an instance of A, there is an algorithm for transforming instances of A into instances of B. This is often done to derive hardness results: if ...

Webb10 mars 2024 · If a problem is NP and all other NP problems are polynomial-time reducible to it, the problem is NP-complete. Thus, finding an efficient algorithm for any NP-complete problem implies that an efficient algorithm can be found for all such problems, since any problem belonging to this class can be recast into any other member of the class.
