DPLL Boolean Satisfiability Solver for .NET

NanoByte SAT Solver is a DPLL Boolean Satisfiability Solver for .NET.
Add a reference to the NanoByte.SatSolver NuGet package to your project. It is available for .NET Framework 2.0+ and .NET Standard 1.0+.
You need to choose the underlying type to use for Literals in Boolean Formulas. This will often be int
or string
but you can also use any other type that implements the IEquatable<T>
interface. You can then create an instance of Solver<T>:
The library enables you to express Boolean Formulas using implicit casting and operators for humanfriendly sample and test code:
For constructing Formulas at runtime you can use a collectionlike interface instead:
Finally, you can use the solver to determine whether a Formula is satisfiable:
When the Solver needs to choose a Literal to assign a truth value to during backtracking, it simply picks the first unset Literal from the list. You can replace this with your own domainspecific logic for better performance by deriving from Solver<T> and overriding the ChooseLiteral() method.
