  2. Expression (mathematics) - Wikipedia

    en.wikipedia.org/wiki/Expression_(mathematics)

    A formal expression is a kind of string of symbols, created by the same production rules as standard expressions, however, they are used without regard to the meaning of the expression. In this way, two formal expressions are considered equal only if they are syntactically equal, that is, if they are the exact same expression.

  3. Binary expression tree - Wikipedia

    en.wikipedia.org/wiki/Binary_expression_tree

    Two common types of expressions that a binary expression tree can represent are algebraic [1] and boolean. These trees can represent expressions that contain both unary and binary operators. [1] Like any binary tree, each node of a binary expression tree has zero, one, or two children.

  4. Algebraic expression - Wikipedia

    en.wikipedia.org/wiki/Algebraic_expression

    An algebraic equation is an equation involving polynomials, for which algebraic expressions may be solutions. If you restrict your set of constants to be numbers, any algebraic expression can be called an arithmetic expression. However, algebraic expressions can be used on more abstract objects such as in Abstract algebra.

  5. Polynomial evaluation - Wikipedia

    en.wikipedia.org/wiki/Polynomial_evaluation

    For evaluating the univariate polynomial + + +, the most naive method would use multiplications to compute , use multiplications to compute and so on for a total of (+) multiplications and additions. Using better methods, such as Horner's rule , this can be reduced to n {\displaystyle n} multiplications and n {\displaystyle n} additions.

  6. Lazy evaluation - Wikipedia

    en.wikipedia.org/wiki/Lazy_evaluation

    Evaluating this lambda expression is similar [a] to constructing a new instance of an anonymous class that implements Lazy<Integer> with an eval method returning 1. Each iteration of the loop links a to a new object created by evaluating the lambda expression inside the loop.

  7. Polynomial - Wikipedia

    en.wikipedia.org/wiki/Polynomial

    An even more important reason to distinguish between polynomials and polynomial functions is that many operations on polynomials (like Euclidean division) require looking at what a polynomial is composed of as an expression rather than evaluating it at some constant value for x.

  9. Short-circuit evaluation - Wikipedia

    en.wikipedia.org/wiki/Short-circuit_evaluation

    Short-circuit evaluation, minimal evaluation, or McCarthy evaluation (after John McCarthy) is the semantics of some Boolean operators in some programming languages in which the second argument is executed or evaluated only if the first argument does not suffice to determine the value of the expression: when the first argument of the AND function evaluates to false, the overall value must be ...
