For each of the following, decide whether the claim is True or False and select the True ones:
Suppose we discover that the 3SAT can be solved in worst-case cubic time. Then it would
mean that all problems in NP can also be solved in cubic time.
If a problem can be solved using Dynamic Programming, then it is not NP-complete.
Suppose X and Y are two NP-complete problems. Then, there must be a polynomial-time
reduction from X to Y and also one from Y to X.
Maximum Independent Set problem is known to be NP-Complete. Suppose we have a graph G in
which the maximum degree of each node is some constant c. Then, is the following greedy
algorithm guaranteed to find an independent set whose size is within a constant factor of the
optimal?
1) Initialize S = empty
2) Arbitrarily pick a vertex v, add v to S
delete v and its neighbors from G
3) Repeat step 2 until G is empty
Return S
Yes
No
