Advanced Topic 40 of 51 Theory & Discrete Math

SAT Problem

Deciding whether a Boolean formula can be satisfied.

How it works

Given a Boolean formula, does an assignment make it true? 3-SAT is NP-complete while 2-SAT is in P. Modern CDCL solvers handle millions of variables in practice.

Where it is used

Hardware verification, planning, scheduling.

Common pitfall

Worst-case hardness does not rule out fast solvers on structured instances.

Where it fits in the course

SAT Problem is topic 40 of 51 in Theory & Discrete Math, rated Advanced. It follows P vs NP. The next topic is Space Complexity Classes.
