A tag is a keyword or label that categorizes your question with other, similar questions. Using the right tags makes it easier for others to find and answer your question.
Algorithms for finding an element in some specified data-structure (most commonly, in a tree).
Questions about general methods and techniques for proving multiple theorems. When asking about the proof of a single statement, use tags relating to what the proof is about instead.
Satisfiability (SAT) is the problem of determining whether there is a variable assignment that fulfills a given Boolean formula.
