WebBefore a combinatorial problem can be solved by current SAT methods, it must usually be encoded in conjunctive normal form, which facilitates algorithm implementation and allows a common file format for problems. WebIn this course you will learn how to apply satisfiability (SAT/SMT) tools to solve a wide range of problems. Several basic examples are given to get the flavor of the applications: fitting …
