The satisfiability (SAT) problem is an important problem of automated reasoning. In the past decades, many methods of SAT are proposed, such as method based on resolution, method based on tableau and method based on extension rule. Based on the study of extension rule, we find that the SAT problem can be solved with hitting set algorithms. If we can find a hitting set of a clause set, and if there...
The platform of intelligent test is one of the core content for modern distant education system. The reasonable evaluation of intelligence test is the key technology for the embodiment of excellence in intelligent test platform. In this paper, in order to more accurately analyze and evaluate the students' distance learning behavior, process and achievement, we design a remote intelligent test platform,...
Methodology is the theory of methods in recognizing and reforming the world. It is divided into three layers: philosophy methodology, general science methodology and concrete science methodology. System methodology as one of the basic methods that research computer science, is a general science methodology. This paper aims to discuss the fundamental principles of system methodology, at the same time,...
Statistical default logic is an expansion of classical (i.e. Reiter's) default logic that allows us to model common inference patterns found in standard inferential statistics, which is an expansion with an error-bound parameter. This paper proposes statistical default inference based on dynamic fuzzy logic (DFL) and constructs a method of computing extensions of fuzzy statistical default theory.
