The idea that proofs are objects capable of being treated by a mathematical theory is due to Hilbert. Proofs are represented as derivations, or deductions, i.e. finite and labeled trees which are build up according to a set of rules; these rules are provided by a formal system and change from one system to another. Structural Proof Theory studies the properties of deductions as combinatorial st...

Multiple processors can be used to speed up a backward-chaining deduction by distributing or-parallel deductions. However, the actual speedup obtained is strongly dependent on the amount of communication required for the task allocation strategy. A Variable Supply Model (VSM) is presented for multiple processors with replicated databases on a broadcast network. The term model refers to the set ...

Using semantics to guide ATP systems is an under-utilised technique [10]. Two systems that have successfully employed semantic guidance are CLIN-S [1] and SCOTT [5]. In linear deduction, semantic guidance has received only limited attention, e.g., [7, 8]. Our research is developing semantic guidance for linear deduction in the Model Elimination (ME) [3] paradigm. Search pruning, at the possible...

Background: Standards-based prescribing can increase the effectiveness of treatment and optimal management financial resources, including reducing costs insurance deductions. Therefore, deductions is necessary for pharmacy management. So, this study aimed to analysis prescriptions governmental Lorestan University Medical Sciences. Materials Methods: This a retrospective cross-sectional that inc...

Simulators and analyzers for protocols do not distinguish between the local ’subjective’ view of the agents and the global ’objective’ view of the analysis perspective. In practice this means that security analysis in general and protocol analysis in particular do neither model the agents local beliefs nor their local deduction power in a satisfactory way. This paper suggests a solution to the ...
