Some synergized clause selection strategies for contradiction separation based automated deduction

The synergized dynamic contradiction separation based automated deduction theory has provided a novel logic based automated deduction reasoning framework, which ex­tends the static binary resolution inference rule to a dynamic multiple contradiction separation based automated deduction mechanism. This novel contradiction separation based auto­mated deduction mechanism is characterized as a dynamic, multi-clauses involving, synergized, goal-oriented and robust automated reasoning framework. In order to further improve the efficiency and feasibility of this novel automated deduction mechanism, this paper proposes some strategies for clause or literal selection during the automated deduction process, which consider mainly the synergized effect of multi-clauses during the deduction process. Some examples are put forward to illustrate the feasibility of these proposed strategies.
