Boolean expression

노트

• The IDE will warn you if the boolean expression has some unnecessary parts and could be simplified – press Alt+Enter to do that.
• Complete the expression by entering a Boolean expression to evaluate.
• For example, you can use INT and SMALLINT to store the value returned by a Boolean expression.
• When Boolean expressions are evaluated, there are only two possible results: TRUE or FALSE.
• The chapter also discusses how to model English statements as boolean expressions.
• An expression which evaluates to either true or false is called a boolean expression.
• Boolean expressions are used extensively in programming language constructs such as if-then-fi commands and while loops.
• BE-Tree is a novel dynamic data structure designed to efficiently index Boolean expressions over a high-dimensional discrete space.
• Using 4-6 above, we itteratively compute the Truth Tables of any Boolean expression.
• There are a number of important Boolean expressions that are representated by their own operation symbol.
• Formally, the tautology problem is solvable in that we need only construct the truth table for a given Boolean expression.
• If a Boolean expression has propositional variables then the corresponding truth table has rows.
• A Boolean expression enclosed in parentheses Example: (!
• A boolean expression is an expression that evaluates to a boolean value.
• A Boolean expression always produces a Boolean value.
• A Boolean expression is composed of a combination of the Boolean constants (True or False), Boolean variables and logical connectives.
• In computer science, a Boolean expression is an expression used in programming languages that produces a Boolean value when evaluated.
• Parentheses can be used for grouping the parts of complex boolean expressions.
• We also assume a similar syntactic category BExp of Boolean expressions, ranged over by b, b′, etc.
• Furthermore, for every pair of data expressions e, e′ we assume that e = e′ is a Boolean expression.
• to denote its value and use a similar convention for Boolean expressions.
• Boolean expressions can compare data of any type as long as both parts of the expression have the same basic data type.
• A Boolean expression is a three-part clause that consists of two items to be compared, separated by a comparison operator.
• You can create a more complex Boolean expression by joining any of these three-part expressions with the AND and OR logical operators.
• Use the NOT operator, with parentheses around the expression, to reverse the sense of a Boolean expression.
