What You Need To Know About Biliniar Problem

By Matthew Fox


As a matter of fact, some people are actually familiar the linear systems often used in engineering or simply in sciences. In most cases, they are presented as vectors. These kind of systems or problems may be extended to different forms where variables are usually partitioned into two disjointed subsets. In such a case the left side is linear on every separate set. As a result, it gives rise to the optimization problems when having the bilinear goals together with either one or several constraints known as biliniar problem.

Generally, bilinear problems are composed of quadratic function subclasses or even sub-classes of quadratic programming. Such programming can be applied in various instance such as when handling constrained bimatrix games, the handling of Markovian problems of assignment as well as in dealing with complementarity problems. In addition, many 0-1 integer programs can be expressed in the form described earlier.

Usually, some similarities may be noted between the linear and the bi-linear systems. For example, both systems have homogeneity in which case the right hand side constants become zero. Additionally, you may add multiples to equations without the need to alter their solutions. At the same time, these problems can further be classified into other two forms that include the complete as well as the incomplete forms. Generally, the complete form usually have distinct solutions other than the number of the variables being the same as the number of the equations.

On the contrary, incomplete forms usually have an indefinite solution that lies in some specified range, and contain more variables compared to the number of equations. In formulating these problems, various forms can be developed. Nonetheless, a more common and practical problem includes the bilinear objective functions that are bound by some constraints that are linear. All expressions taking this form usually have a theoretical result.

Such programming problems may as well be expressed as concave minimization problems. This is because of their importance when coming up with concave minimizations. Two main reasons exist for this. To begin with, the bilinear programming can be applied to numerous problems in the real world. The second is that some of the techniques utilized when solving bilinear programs bear similarities with the techniques applied in solving general concave problems on minimization.

These programming problems may be applied in several ways. These applications are such as in models which try to represent circumstances the players of bimatrix games often face. It has also been used previously in decision making theory, locating newly acquired equipment, multi-commodity network flow, multi-level assignment issues and scheduling orthogonal production.

Additionally, optimization problems involving bilinear programs may also be necessary in petroleum blending activities and water networks operations all over the world. The non-convex bilinear constraints are also highly needed in modeling the proportions that are to be mixed from the different streams in petroleum blending as well as in water network systems.

The pooling problem as well make use of these forms of problems. Their application also include solving various planning problems and multi-agent coordination. Nonetheless, these generally places focus on numerous features of the Markov process that is commonly used in decision-making process.
