Universal calculator

The UniCalc solver was designed by the Russian Research Institute of AI to solve arbitrary systems of algebraic relations. Here, a relation is considered to be an equation, inequality or a logical expression. According to the algorithm used, the system to be solved can be either overdetermined or underdetermined, and the system's parameters (coefficients, variables) can be imprecise and expressed as intervals. Such a system may contain only integer and real variables or combine both integer and real variables.

As a result of solving algebraic systems, we either find a parallelepiped that contains all roots of the system, or a message about the system's incompatibility is issued. If the system has a single root, then the parallelepiped will be reduced to a point (with a given accuracy). If the system has several roots, it is necessary to add the appropriate relations, or use the built-in tool for automatic root locating - in order to locate each of them.

The solver is an integrated environment supporting input of the system to be solved, its modification, calculations, viewing results, specifying accuracy, etc. To input and modify the system UniCalc has the built-in text editor. To write the problems, a source language close to the commonly used mathematical notation is provided. All problems are processed with the above algorithm. To translate the source input into a network, the solver includes a translator and symbolic pre-processor.
