Assume that the loop gains of second-order DPLL
are [K.sub.0f] and [K.sub.1f], respectively.
The strength of consistency achieved by the unit propagation rule is reflected in the DPLL
performance in many problems.
State-of-the-art SAT solvers are based on DPLL
* Hitless reference switching--if the reference the DPLL
is locked to fails, the DPLL
will lock to another available reference without phase disturbances at its output.
The Principle of Bit Synchronization Clock Extraction Based on DPLL
In the present work we introduce a new parallel carrier recovery algorithm which combines a novel low-latency parallel DPLL
with a traditional feedforward CPR algorithm.
It exploits the complementarity of different sequential DPLL
strategies to let them compete and cooperate on the same formula.
The Model Evolution Calculus as a First-Order DPLL
In the crafted category, the best "brute force" solver usually wins, that is, the CDCL (or plain DPLL
) (Davis, Logemann, and Loveland 1962) solver with the fastest exploration of the search space.
The first, by Martin Davis, professor emeritus at New York University, USA, chronicled the original development of the Davis-Putnam-Loveland-Logemann (DPLL
) algorithm and proposed an unorthodox take on the P = NP problem.
The resulting instance of E-MAJSAT is solved with the Davis-Putnam-Logemann-Loveland (DPLL
) algorithm (Davis, Logemann, and Loveland 1962).
Systematic SAT Solvers Although it was discovered many years ago, the DPLL
algorithm (Davis, Logemann, and Loveland 1962) remains a central algorithm, and it can be summarized with a minimum of background.
