Boolean algebra is a branch of mathematics that deals with variables that have two possible values: true and false, often represented as 1 and 0, respectively. It was introduced by the mathematician George Boole in the mid-19th century. Boolean algebra is fundamental in the field of computer science, digital logic design, and various areas of engineering because it provides the underlying principles for how computer circuits and data are manipulated.
In logic, particularly in propositional logic and predicate logic, "normal forms" refer to standardized ways of structuring logical expressions. Two of the most commonly discussed normal forms are: 1. **Conjunctive Normal Form (CNF)**: - A logical formula is in conjunctive normal form if it is a conjunction (AND) of one or more clauses, where a clause is a disjunction (OR) of literals.
A 2-valued morphism typically refers to a concept in mathematics, particularly in category theory and related areas such as logic or computer science. However, the term might not have a universally accepted definition and can vary depending on the context it is used in.

The problem can be expressed in terms of propositional logic, where the formula is composed of variables, logical operators (AND, OR, NOT), and constants (TRUE, FALSE). SAT solvers are algorithms designed to solve the SAT problem, and they often employ various heuristics to improve performance and efficiency.
