42 results about "Set packing" patented technology

Set packing is a classical NP-complete problem in computational complexity theory and combinatorics, and was one of Karp's 21 NP-complete problems. 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). More formally, given a universe U and a family S of subsets of U, a packing is a subfamily C⊆S of sets such that all sets in C are pairwise disjoint.
