SAT
The first problem proven to be NP-complete. It asks whether there exists an assignment of Boolean variables that makes a given Boolean formula true, and it is the classic representative of the P versus NP problem.

SAT (the Boolean satisfiability problem) is the first problem proved to be NP-complete.
A backdoor set is a concept in SAT solving: there exists a set of variables such that, once assigned specific values, the remaining formula can be solved in polynomial time.
After encoding the agent routing graph as k-CNF, "does a deadlock path exist" is equivalent to asking whether the formula is satisfiable (SAT).
NP-complete problems are the hardest class within NP, and any NP problem can be reduced to them in polynomial time; classic examples include the decision version of the traveling salesman problem, the Boolean satisfiability problem (SAT), and the 3-coloring problem for graphs.
GJK (Gilbert–Johnson–Keerthi) and SAT (Separating Axis Theorem) are the two most commonly used methods in real-time collision detection.
SAT enumerates all possible separating axes (generated by face normals and edge cross products), and the more faces there are, the more axes need to be tested.
The calculator policy for the SAT is set by the College Board, while AP exams have policies determined separately by each subject committee.
Collision detection algorithms (such as GJK or SAT) can perform geometric intersection operations between the robot's own 3D model and the bounding box of the target space to calculate a feasibility confidence score.
The SAT is a standardized college entrance exam in the United States covering reading, writing, and math, with more than 2 million test-takers each year.
Research by the College Board shows that students from high-income families score approximately 200 points higher on the SAT on average than students from low-income families.
