Question 1.
What is a Boolean variable?
Show hintHide hint
Think about binary options.
Question 2.
Define a clause in the context of Boolean logic.
Show hintHide hint
Recall that literals can be either a variable or its negation.
3Question 3.
What does a clause consist of?
- A conjunction of literals
- A disjunction of literals
- An assignment of truth values
Show hintHide hint
Think about OR and AND definitions.
4Question 4.
True or False: The Boolean satisfiability problem is a decision problem.
- True
- False
Show hintHide hint
Consider the definition of decision problems in computing.
Question 5.
Consider the Boolean formula (x AND y) OR (NOT x AND z). Given the truth assignments: x=true, y=true, z=false; evaluate whether this is a satisfying assignment.
Show hintHide hint
Break down each clause to assess its truth.
Question 6.
Propose a method to transform the Boolean satisfiability problem into a checking problem. Discuss how this transformation assists in understanding computational difficulties.
