Not A - Internet is packet-switched, not circuit-switched. The packets might follow different paths.
Not B - The routers communicate with each other to determine the path.
C correct - The Internet Protocol or IP used by routers to send packets makes no guarantee that they will be delivered. It uses best-effort delivery.
Not D - See answer B above.
Is it bit-depth maybe????
Answer:
See explaination
Explanation:
Diverse Subset Problem is NP: When presented with a set of k customers, it can be checked in polynomial time that you wont at any time have two customers in the set have ever bought the same product.
Independent Set is known to be NP-complete.
Independent Set ?P Diverse Subset Problem: Suppose we have a black box for Diverse Subset Problem and want to solve an instance of Independent Set. For our Independent Set Problem, we have a graph G=(V,E) and a number k, and need to find out if G contains an independent set of size (at least) k. We need to reduce the Independent Set Problem to a Diverse Subset Problem. We do this by constructing an array where each v in V is a customer and each e in E is a product, and customer v purchased every product e for which the product edge e touches the customer node v. Then we ask the black box for the Diverse Subset Problem if there is a subset of k customers that is diverse.
The black box for the Diverse Subset Problem will return.
You gave the answer in your question
Ummm what is the question
