Homework Answers

Answer #1

1. The MIN VERTEX COVER problem is in ??. FALSE
Explanation: MIN VERTEX COVER problem is  optimization problem of finding a minimal(least) vertex cover in the provided graph. MIN VERTEX COVER problem is NP-complete

2. The MIN VERTEX COVER problem is ??-hard. FALSE
explanation: MIN VERTEX COVER problem is  optimization problem of finding a minimal(least) vertex cover in the provided graph. MIN VERTEX COVER problem is NP-complete . where NP-hard is not a decision problem , NP-complete is exclusively a decision problem.
