... One important distinction to make is that fuzzy logic is NOT probability. Although both employ values between 0 and 1 that represent something about the symbol or event, it is the meaning of this number that differs. In probability, the number represents the likelihood of an event’s occurrence. In f ...

... satisfiable, it adds that index (or the set of truth assignments that work) to an array for later use. The second for loop goes through the satisfied array, and checks if all those are satisfiable. If it is satisfiable, that means the first expression must entail the second expression. Here is an ex ...

Equivalently, consider the column C1 of truth-values beneath the clause and the column C2 of truth-values underneath the rest of the formula in the formula’s truth table: In any row where there i ...

At the semantic level, we will be working in the style of mathematical proof you’re used to, even as we attempt to formalize it in stages. Ideally, we would like to reach the point where ...

... Fix a language L and fix a tuple of variables x from a sequence of sorts S. We define a pseudo-metric on the formulas with free variables x as follows: we define the distance between ϕ(x) and ψ(x) to be sup{|ϕM (a) − ψ M (a)| : M, an L-structure, and a ∈ M} We will call this space FS . This can also ...
