NP – If A is NP-hard, then B is NP-hard. We can show that problems are NP-complete via the following steps. 1. Show X ∈ NP. Show that X ∈ NP by finding a nondeterministic algorithm, or giving a valid verifier for a certificate. 2. Show X is NP-hard. Reduce from a known NP-complete problem Y to X. This is sufficient because all problems ...

Definition: A language B is NP-complete if: 1. B ∈NP 2. Every A in NP is poly-time reducible to B That is, A ≤ P B When this is true, we say B is NP-hard Last time: We showed 3SAT ≤ P CLIQUE ≤ P IS ≤ P VC ≤ P SUBSET-SUM ≤ P KNAPSACK All of them are in NP, and 3SAT is NP-complete, so all of these problems are NP-complete!

in which after multiplying an input array by alphasome output values exceed 255. Because when we a pass a NumPy array with the data type np.uint8as input we expect that we will also get an array with the np.uint8data type as output and that means that output values should not exceed 255 (which is the maximum value for this data type).

Proof: Let s(Bi) be the sum of sizes of the items assigned to bin Bi in the Next Fit solution. For any two adjacent bins (Bj and Bj+1), we know that s(Bj) + s(Bj+1) > 1.
