We can implement states using new variables as state indicators.

The algorithm has a new variable, S, whose value is such a pair.

It occurred to him that he was a new variable in an already complex equation.

Rather, allow me to introduce a new variable into the equation.

In late 2008, a new variable came into play.

The situation is complicated enough without introducing a new variable.

He needed a moment to reconsider the situation in light of this new variable.

In this week's Nature, a paper suggests a new variable to consider: the climate.

A new variable in the equation would be the last thing he wanted.

He insisted on the need for a new variable, the number of photons.
