Suppose one has a finite set S and a list of subsets of S. Then, the set packing problem asks if some k subsets in the list are pairwise disjoint (in other words, no two of them share an element).

Since SET … WebThe following is the proof that the problem VERTEX COVER is NP-complete. This particular proof was chosen because it reduces 3SAT to VERTEX COVER and involves the transformation of a boolean formula to something geometrical. This is similar to what will be done for the two art gallery proofs. WebSet-Coveris NP-Complete. However, there is a simple algorithm that gets an approximation ratio of lnn (i.e., that finds a cover using at most a factor lnn more sets than the optimal solution). Greedy Algorithm (Set-Cover): Pick the set that covers the most points. Throw out all the points covered. Repeat. ford auto sleepers motorhomes
