For him, painting is a set of physical variables and he has spent a career playing with them.

There might even be some positive correlations between these two sets of variables.

But the shift was actually only from one limited set of variables to another.

A most intriguing set of variables with which to deal.

This set of random variables represents the risk at hand.

The set of variables that are used in s before any assignment.

Another set of variables involves who will represent the Palestinians.

The algorithm is also based on a given set of variables.

For instance, the set of local variables with known values is empty.

Then this is done again with a new set of random variables.
