In computer science the variable (and function value) is most often a natural number.

The orientation of an edge is determined by the comparison between the function values on the corresponding two level sets.

This set encodes the problem of deciding a function value.

More formally, let be the optimal objective function value for any restricted instance.

Once again is an upper bound on the objective function value of the up -problem.

An object with a desired symmetry can be produced by choosing for every orbit a single function value.

Labor costs of exactly $10 will cause the objective function value to remain the same.

The problem of generating function values which are accurate to the last bit is known as the table-maker's dilemma.

Rangekeepers used a number of cams to generate function values.

The solution with the function value can be found after 325 function evaluations.
