Integer Range

Used to define a group of integers.

For example, to declare a decision variable x that can take values between 1 and 10, you can do the following:

Which would produce the following Essence Output:

find  x : int (  0 .. 10  ) 

Note

Notice in the blocks example above, we define the range to be 0 to 10.

Say that you want a range A to B where A and B are some integers. Your bounds must extend one step outside of that range. So the lower bound would be A - 1 and the upper bound would be B.
