Chemistry Solver is designed to solve complex problems on which a trial-and-error approach might be used, such as balancing complex equations, curve fitting, building mathematical models from empirical data, improving reaction efficiency, solving coupled sets of nonlinear partial differential equations, and training neural networks. Based on genetic algorithms, Chemistry Solver uses data from an Excel spreadsheet to find the optimal solution to the problem. System requirements include a PC with at least a 386 processor, 2 MB RAM, Windows 3.1 or Windows 95, and Microsoft Excel.
