AutoAbacus is a powerful equation solving library that finds solutions to equation sets. Equations are passed to AutoAbacus as text, and the program attempts to find a solution that satisfies all constraints. The equations can be linear or polynomial, and can include arbitrary functions. By profiling the types of equations in the system and their dependencies on each other, AutoAbacus uses appropriate solution methods to solve individual subsets of equations. Applications range from use in a business rules engine to solving engineering equation systems.
