SUBSET-SUM is NP-Complete •The SUBSET-SUM problem:–Instance: We are given a set S of positive integers, and a target integer t.–Question: does there exist a subset of S adding up to t?•Example: {1, 3, 5, 17, 42, 391}, target 50 –The subset sum problem is a good ...

And the reduction can be computed in polynomial time because of the uniformity of C.Theorem2SAT is NP-complete.Proof It is clear that SAT is in NP:guess an assignment an evaluate the formula as if it was a circuit.To show that SAT is NP-complete we reduce CIRCUIT-SAT to SAT.1 ...
The subset sum problem is a well-known NP-complete problem in which we wish to find a packing (subset) of items (integers) into a knapsack with capacity so that the sum of the integers in the packing is at most the capacity of the knapsack and at least a given integer threshold. In...
As one of Karp’s 21 NP-complete problems, the subset sum problem, as well as its generalization, has been well studied. Among the rich literature, there is little work on the online version, where items arrive over list and irrevocable decisions on packing them or not must be made immedi...
The research literature on NP-complete problems includes some attempts to identify easier and harder problems within the class, and the results with respect to Subset Sum are not particularly conclusive. If the complexity parameter is the cardinality of the set S1, the problem appears to be strong...
The planar graph 3-colorability (P3C) is one of {bf NP}-complete problem. Duo to probably appearing the second type of mistake in setting colors, a computational algorithm might repeat many times to decide whether it can correct wrong coloring in many examined subgraphs. Then one can turn P3...
As a proof of principle, we focused on ELF1, which is not affected by DOT1Li at either the transcriptional or protein level (Fig.4a–b). We hypothesized that if loss of H3K79me2/3 at KEEs created an environment that was generally repressive for TF binding, we should observe reduced ...
