Text Algorithms

---

One of the simplest and natural types of information representation is by means of written texts. Data to be processed often does not decompose into independent records. This type of data is characterized by the fact that it can be written down as a long sequence of characters. Such linear sequence is called a text. The texts are central in "word processing" systems, which provide facilities for the manipulation of texts. Such systems usually process objects which are quite large. For example, this book contains probably more than a million characters. Text algorithms occur in many areas of science and information processing. Many text editors and programming languages have facilities for processing texts. In biology, text algorithms arise in the study of molecular sequences. The complexity of text algorithms is also one of the central and most studied problems in theoretical computer science. It could be said that it is the domain where the practice and theory are very close together.
