A solver takes problem descriptions in some sort of generic form and calculates their solution. In a solver, the emphasis is on creating a program or library that can easily be applied to other problems of similar type. Types of problems with existing dedicated solvers include:. In the case of a single equation, the 'solver' is more appropriately called a., which are a special case of non linear systems, better solved by specific solvers.

The ( GPS) is a particular computer program created in 1957 by, and intended to work as a universal problem solver, that theoretically can be used to solve every possible problem that can be formalized in a symbolic system, given the right input configuration.
In this post I am going to cover the new user interface for the Solver app, the new solving methods and constraints that can be used, and the new reports that can be generated. New Interface One of the changes that we have made is to the interface used for setting the Solver Parameters. To get Solver on Excel 2003, go to the Tools menu, and click Add-Ins. In the Add-Ins available list, check the Solver Add-in box, and click OK. If Excel displays a message that the Solver Add-in is not currently installed on your computer, click Yes to install it.
It was the first computer program which separated its knowledge of problems (in the form of rules) from its strategy of how to solve problems (as a general search ). General solvers typically use an architecture similar to the GPS to decouple a problem's definition from the strategy used to solve it. The advantage in this decoupling is that the solver doesn't depend on the details of any particular problem instance. The strategy utilized by general solvers was based on a general algorithm (generally based on ) with the only goal of completeness.
This induces an exponential that dramatically limits their usability. Modern solvers use a more specialized approach, which takes advantage of the structure of the problems that the solver aims to spend as little time as possible backtracking. For problems of a particular class (e.g., systems of ) there are usually a wide range of different algorithms available; sometimes a solver implements multiple algorithms, but sometimes just one.
