A multigraph has two sorts of elements forming a set of vertices and of edges, and has two unary operations giving the source ( start ) and target ( end ) vertices of each edge.
12.
The PORS language consists of two terminal nodes ( 1 and recall ), one unary operation ( store ) and one binary operation ( plus ) that together make up a parse tree that calculates a number.
13.
Algebraic structures may be viewed in different ways, however the common starting point of algebra texts is that an algebraic object incorporates one or more sets with one or more binary operations or unary operations satisfying a collection of axioms.
14.
The ubiquitous group, namely, which is taken as an axiom in the more general context of a semigroup with involution, has sometimes been called an "'antidistributive property "'( of inversion as a unary operation ).
15.
As a unary operation, taking the inverse ( sometimes called "'inversion "') commutes with the order-related operations of relation algebra, i . e ., it commutes with union, intersection, complement etc.
16.
It did so by having unary operations operate on the X register, addition and subtraction operate on the X and Z registers, and multiplication, division, power, and root functions operate on the X and Y registers in its operational stack.
17.
An effect algebra consists of an underlying set " A " equipped with a partial binary operation ?", a unary operation ( " ) ?", and two special elements 0, 1 such that the following relationships hold:
18.
It has four unary operations, two of which are constant operations, another is the identity, and the most commonly used one, called " negation ", returns the opposite of its argument : 1 if 0, 0 if 1.
19.
Note that there is a close relation between reducing binary quadratic forms and continued fraction expansion; one step in the continued fraction expansion of a certain quadratic irrationality gives a unary operation on the set of reduced forms, which cycles through all reduced forms in one equivalence class.
20.
Examples of quasi-regular semirings are provided by the Kleene algebras ( prominently among them, the algebra of regular expressions ), in which the quasi-inverse is lifted to the role of a unary operation ( denoted by " a " * ) defined as the least fixedpoint solution.
