Study Notes
Formal Language Theory
- In formal language theory, an alphabet is a finite set of symbols, letters, or characters used to form strings or words.
- Example of a binary alphabet: {0, 1} (the set of binary digits used in computer science).
Strings and Cardinality
- Strings are finite sequences of symbols from an alphabet.
- The cardinality of an alphabet refers to the number of symbols it contains.
Restrictions on Alphabets
- It is often necessary to restrict the symbols in an alphabet to ensure that the set of symbols is finite and manageable.
Discrete Mathematics
- Discrete mathematics studies discrete objects, which are distinct and individual, rather than continuous.
- Discrete mathematics is characterized by the study of individual, distinct elements rather than continuous variables.
- The term "managerial mathematics" is sometimes applied to parts of discrete mathematics relevant to business.
Historical Development
- The latter half of the twentieth century saw an increase in research in discrete mathematics due to the development of computer science.
Sets in Discrete Mathematics
- Discrete mathematics primarily deals with countable sets, which are sets with the same number of elements as some subset of the natural numbers.
