  • Caching

    “Representation is the essence of programming” Frederic P. Brooks Jr., “The Mythical Man-month” Looking through the literature on SAT solvers, it is rare to find any algorithm that uses a form of time-memory trade-off. In fact, it is rare to find any algorithm that uses too much memory. This also shows up in practice, as […]

  • CryptoMiniSat 2.6.0 released

    Version 2.6.0 of the CryptoMiniSat SAT solver has been released. The new release incorporates a number of important additions and discoveries. Additions include a better memory manager and better watchlists, while the discoveries include an interesting use of asymmetric branching and an on-the-fly self-subsuming resolution algorithm. The new solver can now solve 221 problems from […]

  • Asymmetric branching

    Asymmetric branching is an algorithm that shortens CNF clauses in SAT Solvers. A clause, for instance v1 V v2 V v3 V v4 (where letters are binary variables and V represents binary OR) could possibly be shortened to v1 V v2 V v3. To find out if it can be, all we have to do […]
