Clarification of P and NP classes, the concept of NP-completeness, and the SAT problem.
- P problems are solvable in polynomial time, whereas NP problems are verifiable in polynomial time but may be harder to solve.
- NP-completeness signifies a class of difficult NP problems that, if solved, would resolve the P vs NP question.
- The Boolean Satisfiability problem (SAT) is a key NP-complete problem; solving it efficiently would prove P equals NP.

The challenges faced by researchers in proving whether P equals NP or not.
- Most computer scientists believe P does not equal NP, but proving this has been difficult due to mathematical barriers.
- Circuit complexity and the Natural Proofs Barrier are significant obstacles in establishing the non-equivalence of P and NP.
- Meta-complexity and the Minimum Circuit Size Problem (MCSP) research are current focuses in the quest to understand computational limits.
