Many functions that we'll discuss that are used with core.logic (such as membero) are somewhat special - in fact they have little meaning outside of run/run*. In order to differentiate these special functions (relations) from regular Clojure functions, we often append an "o", "e", "u...
SimpleAuth pluginThis very simple plugin adds a custom step called :authorize, that can be used to check for permissions and halt the operation with a :forbidden error when they aren't fulfilled.In order to use it you must define a boolean predicate to check for permissions, by passing a ...

A particular theory of DD exploited here is essentially based on the approach of Russell, but with descriptions treated as genuine terms. However, the reductionist aspect of the Russellian approach is retained in several ways. Moreover, a special form of tense definite descriptions is formally ...
athe dynamic rarely follows the logic of a simple problem-solving sequences where the problem is identified, a gap in knowledge specified and then filled by experimental research and afterward the policy is enacted in the light of this information. 动态在指定的知识很少跟随逻辑简单的解决问题的序列...
in Sect.1we will briefly take a look at Cresswell’s case forPremise 1(Cresswell scholars can safely skip Sect.1and move directly to Sect.2). SincePremise 2relies on a comparison of certain formal languages in terms of their expressive power, in Sect.2we provide a formal definition of th...
A first idea is to exploit refined or generalized scales, or yet allows weights to have unknown, or variable values, while preserving classical logic formulas and weights interpreted in terms of necessity measures. Variable weights enables a form of hypothetical reasoning to be captured, as well ...
simple example is(6) Nothing is both anXand a non-X.Formal logic is concerned with proposition forms as well as with inference forms. The study of proposition forms can, in fact, be made to include that of inference forms in the following way: let the premises of any given inference ...
Fuzzy logic is a generalization from standard logic, in which all statements have a truth value of one or zero. In fuzzy logic, statements can have a value of partial truth, such as 0.9 or 0.5. Theoretically, this gives the approach more opportunity to mimic real-life circumstances, where ...
