Equation solving with PCs

There are two stages in equation solving. These are localization of solutions and their refinement. Many methods ignore problems concerning localization. Generality of methods falls quickly with growth of system complexity. Then a random search guided by heuristics may be some cure to complex system solving. An algorithm is proposed here in the form of Turbo Pascal program. It is composed of three methods. The program user controls system solving in function of system complexity.
