Grand Theft Auto 5 is not just a video game franchise. It is an embodiment for an entire genre of video games. It's an in depth tale of prison minded maniacs on a self-destructing trajectory to hell. The game is set largely inside the superficially glitzy city of Los Santos. It mirrors the blood-splattered lives of many in Los Angeles. With some of the most astounding imagery of the dense downtown Los Santos with all its soaring skyscrapers and garbage crammed alley-ways. This is not simply one other pleasant sport, but also a becoming satire of latest American life.
In [[mathematics]] and specifically in [[algebraic geometry]], the '''dimension''' of an [[algebraic variety]] may be defined in various equivalent ways.  


Some of these definitions are of geometric nature, while some other are purely algebraic and rely on [[commutative algebra]]. Some are restricted to algebraic varieties while others apply also to any [[algebraic set]]. Some are intrinsic, as independent of any embedding of the variety into an [[affine space|affine]] or [[projective space]], while other are related to such an embedding.
The multi-pronged user interface of the game, permits the user to play the same mission in several ways. It is without any doubt on the pinnacle of open world video game design. The Grand Theft Auto franchise is a British online game series that was created originally by programmers David Jones and mike daily. It was later joined by brothers Dan and Sam Houser in addition to sport designer Zachary Clarke.

The game play is all the time open world permitting player to choose missions packed with motion-adventure, third person capturing, stealth, racing and at instances position playing. From its origin in 1997 there are actually ten stand-alone games and four expansion packs. In each recreation within the series the participant takes on the role of a criminal or wannabe crime lord who sits on the top of organized crime as the game progress.


Let ''K'' be a [[field (mathematics)|field]], and ''L'' ⊇ ''K'' be an algebraically closed extension.

The dimension of ''V'' is any of the following integers. It does not change if ''K'' is enlarged, if ''L'' is replaced by another algebraically closed extension of ''K'' and if ''I'' is replaced by another ideal having the same zeros (that is having the same [[radical of an ideal|radical]]). The dimension is also independent of the choice of coordinates; in other words is does not change if the ''x''<sub>''i''</sub> are replace by linearly independent linear combinations of them. The dimension of ''V'' is

* ''The maximal length'' <math>d</math> of the chains <math>V_0\subset V_1\subset \ldots \subset V_d</math> ''of distinct nonempty subvarieties.''
This definition generalizes a property of the dimension of a [[Euclidean space]] or a [[vector space]]. It is  thus probably the definition that gives the easiest intuitive description of the notion.
* ''The [[Krull dimension]] of A.''
This is the transcription of the preceding definition in the language of [[commutative algebra]], the Krull dimension being the maximal length of the chains <math>p_0\subset p_1\subset \ldots \subset p_d</math> of [[prime ideal]]s of ''A''.
* ''The maximal Krull dimension of the [[local ring]]s at the points of V''.
This definition shows that the dimension is a ''local property''.
* ''If V is a variety, the Krull dimension of the local ring at any [[Singular point of an algebraic variety|regular point]] of V''
This shows that the dimension is constant on a variety
* ''The maximal dimension of the [[tangent space|tangent vector space]]s at the non [[singular point of an algebraic variety|singular point]]s of V''.
This relies the dimension of a variety to that of a [[differentiable manifold]]. More precisely, if ''V'' if defined over the reals, then the set of its real regular points is a differentiable manifold that has the same dimension as variety and as a manifold.
* ''If V is a variety, the dimension of the [[tangent space|tangent vector space]] at any non [[singular point of an algebraic variety|singular point]] of V''.
This is the algebraic analogue to the fact that a connected [[manifold]] has a constant dimension.
* ''The number of [[hyperplane]]s or [[hypersurface]]s in [[general position]] which are needed to have an intersection with V which is reduced to a nonzero finite number of points.''
This definition is not intrinsic as it apply only to algebraic sets that are explicitly embedded in an affine or projective space.
* ''The maximal length of a [[regular sequence]] in A''.
This the algebraic translation of the preceding definition.
* ''The difference between n and the maximal length of the regular sequences contained in I''.
This is the algebraic translation of the fact that the intersection of ''n''-''d'' hypersurfaces is, in general, an algebraic set of dimension ''d''.
* ''The degree of the [[Hilbert polynomial]] of A''.
* ''The degree of the denominator of the [[Hilbert series]] of A''.
This allows, through a [[Gröbner basis]] computation to compute the dimension of the algebraic set defined by a given [[system of polynomial equations]]
* ''If I is a prime ideal (i.e. V is an algebraic variety), the [[transcendence degree]] over K of the [[field of fractions]] of A''.
This allows to prove easily that the dimension is invariant under [[birational equivalence]].

Let ''V'' be a [[projective algebraic set]] defined as the set of the common zeros of a homogeneous ideal ''I'' in a polynomial ring <math>R=K[x_0, x_1, \ldots, x_n]</math> over a field ''K'', and let ''A''=''R''/''I'' be the [[graded algebra]] of the polynomials over ''V''.
 
All the definitions of the previous section apply, with the change that, when ''A'' or ''I'' appear explicitly in the definition, the value of the dimension must be reduced by one. For example, the dimension of ''V'' is one less than the Krull dimension of ''A''.
 
== Computation of the dimension ==
 
Given a [[system of polynomial equations]], it may be difficult to compute the dimension of the algebraic set that it defines.
 
Without further information on the system, there is only one practical method that consists to compute a Gröbner basis and to deduce the degree of the denominator of the [[Hilbert series]] of the ideal generated by the equations.
 
The second step, which is usually the fastest, may be accelerated in the following way: Firstly, the Gröbner basis is replaced by the list of its leading monomials (this is already done for the computation of the Hilbert series). Then each monomial like <math>{x_1}^{e_1}\cdots {x_n}^{e_n}</math> is replaced by the product of the variables in it: <math>x_1^{\min (e_1,1)}\cdots x_n^{\min(e_n,1)}.</math> Then the dimension is the maximal size of a subset ''S'' of the variables, such that none of these products of variables depends only on the variables in ''S''.
 
This algorithm is implemented in several [[computer algebra system]]s. For example in [[Maple (software)|Maple]], this is the function ''Groebner[HilbertDimension]''.
 
== Real dimension ==
{{see also|Complex dimension}}
For an algebraic set defined over the [[real number|reals]] (that is defined by polynomials with real coefficients), it may occurs that the dimension of the set of its real points differs from its dimension. For example, the [[algebraic surface]] of equation <math>x^2+y^2+z^2=0</math> is an algebraic variety of dimension two, which has only one real point (0, 0, 0), and thus the real dimension zero.
 
The '''real dimension''' of a [[real algebraic set]] is the dimension (as algebraic set) of its [[Zariski closure]]. It is equal to the maximum of the dimensions of the [[manifold]]s contained in the set of the real points of the algebraic set.
 
The real dimension is more difficult to compute than the algebraic dimension, and, to date, there is no available software to compute it.
