 Algorithmic Combinatorics on Partial Words

Algorithmic combinatorics on partial words is a specialized area of combinatorics that deals with the study of combinatorial structures that arise from partial words. A partial word can be thought of as a sequence of symbols that may include some "undefined" or "unknown" positions, often represented by a special symbol (like a question mark or a dot). ### Key Concepts: 1. **Partial Words**: These are sequences where some characters are unspecified.
