Satisfiability problem


A problem used as an example in complexity theory. It can be stated thus:
Given a Boolean expression E, decide if there is some assignment to the variables in E such that E is true.
A Boolean expression is composed of Boolean variables, (logical) negation (NOT), (logical) conjunction (AND) and parentheses for grouping. The satisfiability problem was the first problem to be proved to be NP-complete (by Cook).
