function symbols造句

The interpretation of a function symbol is a function.
Terms are variables, constants, and function symbols applied to other terms.
Function symbols having several declarations are called "'overloaded " '.
When no function symbols are used, terms are expressions over reals, possibly including variables.
Injections allow the identity of target objects to be specified in terms of a function symbol.
It's difficult to find function symbols in a sentence. 用function symbols造句挺难的

In mode 3, the user declares what caseframe is to be used for each function symbol.
The Update groups are used to specify the update conditions to change the values of function symbols.
A constraint t1 = t2 can be simplified if both terms are function symbols applied to other terms.
It is also possible to restrict the arities of function symbols and predicate symbols, in sufficiently expressive theories.
The model contains the evaluation of all function symbols; therefore, Skolem functions are implicitly, existentially quantified.
This equivalence is useful because the definition of first-order satisfiability implicitly existentially quantifies over the evaluation of function symbols.
In predicate calculus a literal is an atomic formula or its negation, where an atomic formula is a function symbols.
However, the interpretation of a function symbol must always assign a well-defined and total function to the symbol.
By contrast, for the three-variable fragment of first-order logic without function symbols, satisfiability is undecidable.
Another improvement that may be used is applying the same Skolem function symbol for formulae that are identical up to variable renaming.
