In a set of n elements, the distance d(x,y) (or simply d when unambiguous) between two elements x and y is their
to access the same element, which arguably looks more complicated. Of course, r′ = r + 1, since [z = z′ – 1], [y = y′ – 1], and [x = x′ – 1]. A simple and everyday-life example is positional notation, which the invention of the zero made possible. In positional notation, tens, hundreds, thousands and all other digits start with ...
The problem of deciding whether for a given Datalog program there is an equivalent nonrecursive program (corresponding to a positive relational algebra query, or, equivalently, a formula of positive existential first-order logic, or, as a special case, a conjunctive query) is known as the Datalog boundedness problem and is undecidable.
In other words, the quality of your web search results is directly tied to the query you construct. In this section, we'll begin by examining how to create queries from scratch, starting with basic keyword searches and later exploring the impact of broadening and refining your language.
