'''Quadratic programming''' (QP) is a special type of [[mathematical optimization]] [[optimization problem|problem]]. It is the problem of optimizing (minimizing or maximizing) a quadratic function of several variables subject to linear constraints on these variables.
 
==Problem formulation==
The quadratic programming problem can be formulated as:<ref>{{Cite book | last1=Nocedal | first1=Jorge | last2=Wright | first2=Stephen J. | title=Numerical Optimization | publisher=[[Springer-Verlag]] | location=Berlin, New York | edition=2nd | isbn=978-0-387-30303-1 | year=2006 | page=449 | postscript=<!--None--> }}.</ref>
 
Assume '''x''' belongs to <math>\mathbb{R}^{n}</math> space. Both '''x''' and '''c''' are [[column vectors]] with ''n'' elements (''n''&times;1 matrices), and ''Q''  is a [[Symmetric matrix|symmetric]] ''n''&times;''n'' [[matrix (math)|matrix]].
 
Minimize (with respect to '''x''')
:<math>f(\mathbf{x}) = \tfrac{1}{2} \mathbf{x}^T Q\mathbf{x} + \mathbf{c}^T \mathbf{x}.</math>
 
Subject to one or more constraints of the form:
:<math> A\mathbf{x} \leq \mathbf b </math> (inequality constraint)
:<math> E\mathbf{x} = \mathbf d </math> (equality constraint)
 
where <math>\mathbf{x}^T</math> indicates the vector [[transpose]] of <math>\mathbf{x}</math>. The notation <math> A \mathbf x \leq \mathbf b </math> means that every entry of the vector <math>A \mathbf x</math> is less than or equal to the corresponding entry of the vector <math>\mathbf b</math>.
 
A related programming problem, [[quadratically constrained quadratic program]]ming, can be posed by adding quadratic constraints on the variables.
 
==Solution methods==
 
For general problems a variety of methods are commonly used, including
 
:*[[interior point method|interior point]],
:*[[active set]],<ref name="ioe.engin.umich">{{cite book|last=Murty|first=Katta G.|title=Linear complementarity, linear and nonlinear programming|series=Sigma Series in Applied Mathematics|volume=3|publisher=Heldermann Verlag|location=Berlin|year=1988|pages=xlviii+629 pp.|isbn=3-88538-403-5|url=http://ioe.engin.umich.edu/people/fac/books/murty/linear_complementarity_webbook/ | mr = 949214 }}</ref>
:*[[Augmented Lagrangian method|augmented Lagrangian]],<ref>{{cite journal | first1 = F. | last1 = Delbos | first2 = J.Ch. | last2 = Gilbert | year = 2005 | title = Global linear convergence of an augmented Lagrangian algorithm for solving convex quadratic optimization problems | journal = Journal of Convex Analysis | volume = 12 | pages = 45–69 }}</ref>
:*[[Conjugate gradient method|conjugate gradient]],
:*[[Gradient projection method|gradient projection]],
:*extensions of the [[simplex algorithm]].<ref name="ioe.engin.umich" />
 
Convex quadratic programming is a special case of the more general field of [[convex optimization]].
 
===Equality constraints===
 
Quadratic programming is particularly simple when there are only equality constraints; specifically, the problem is linear. By using [[Lagrange multipliers]] and seeking the extremum of the Lagrangian, it may be readily shown that the solution to the equality constrained problem is given by the linear system:
 
:<math>
\begin{bmatrix}
  Q & E^T \\
  E & 0
\end{bmatrix}
\begin{bmatrix}
  \mathbf x \\
  \lambda
\end{bmatrix}
=
\begin{bmatrix}
  -\mathbf c \\
  \mathbf d
\end{bmatrix}
</math>
 
where <math>\lambda</math> is a set of Lagrange multipliers which come out of the solution alongside <math>\mathbf x</math>.
 
The easiest means of approaching this system is direct solution (for example, [[LU factorization]]), which for small problems is very practical. For large problems, the system poses some unusual difficulties, most notably that problem is never positive definite (even if <math>Q</math> is), making it potentially very difficult to find a good numeric approach, and there are many approaches to choose from dependent on the problem.<ref>[http://scholar.google.com/scholar?hl=en&q=saddle+point+indefinite+constrained+linear Google search.]</ref>
 
If the constraints don't couple the variables too tightly, a relatively simple attack is to change the variables so that constraints are unconditionally satisfied. For example, suppose <math>\mathbf d = 0</math> (generalizing to nonzero is straightforward). Looking at the constraint equations:
 
:<math>E\mathbf{x} = 0</math>
 
introduce a new variable <math>\mathbf y</math> defined by
 
:<math>Z \mathbf{y} = \mathbf x</math>
 
where <math>\mathbf y</math> has dimension of <math>\mathbf x</math> minus the number of constraints. Then
 
:<math>E Z \mathbf{y} = 0</math>
 
and if <math>Z</math> is chosen so that <math>E Z = 0</math> the constraint equation will be always satisfied. Finding such <math>Z</math> entails finding the [[null space]] of <math>E</math>, which is more or less simple depending on the structure of <math>E</math>. Substituting into the quadratic form gives an unconstrained minimization problem:
 
:<math>
\tfrac{1}{2} \mathbf{x}^T Q\mathbf{x} + \mathbf{c}^T \mathbf{x} \quad \Rightarrow \quad
\tfrac{1}{2} \mathbf{y}^T Z^T Q Z \mathbf{y} + (Z^T \mathbf{c})^T \mathbf{y}
</math>
 
the solution of which is given by:
 
:<math>
Z^T Q Z \mathbf{y} = -Z^T \mathbf{c}
</math>
 
Under certain conditions on <math>Q</math>, the reduced matrix <math>Z^T Q Z</math> will be positive definite. It's possible to write a variation on the [[conjugate gradient method]] which avoids the explicit calculation of <math>Z</math>.<ref>{{Cite journal

==Lagrangian duality==
{{See also|Dual problem}}
 
The Lagrangian [[Dual problem|dual]] of a QP is also a QP. To see that let us focus on the case where <math>c=0</math> and Q is positive definite. We write the [[Lagrange multipliers|Lagrangian]] function as
:<math>L(x,\lambda) = \tfrac{1}{2} x^{T}Qx + \lambda^{T}(Ax-b). </math>
Defining the (Lagrangian) dual function <math>g(\lambda)</math>, defined as <math>g(\lambda) = \inf_{x} L(x,\lambda) </math>, we find an [[infimum]] of <math>L</math>, using <math>\nabla_{x} L(x,\lambda)=0</math>
 
<big><math> x^* =  -Q^{-1}A^{T}\lambda. </math></big>
 
hence the dual function is  
:<math>g(\lambda) = -\tfrac{1}{2}\lambda^{T}AQ^{-1}A^{T}\lambda - \lambda^{T}b</math>
hence the Lagrangian dual of the QP is
 
maximize: <math> -\tfrac{1}{2}\lambda^{T}AQ^{-1}A^{T}\lambda - \lambda^{T}b</math>
 
subject to: <math>\lambda \geqslant 0</math>.
 
Besides the Lagrangian duality theory, there are other duality pairings (e.g. Wolfe, etc.).
 
==Complexity==
 
For [[positive-definite matrix|positive definite]] ''Q'', the [[ellipsoid method]] solves the problem in [[polynomial time]].<ref>{{cite journal| last=Kozlov | first=M. K. | coauthors=S. P. Tarasov and [[Leonid Khachiyan|Leonid G.
