Methods and apparatus, including computer systems and program products, for normalizing computer-represented collections of objects. A first minimum value can be normalized based on a second minimum value of a universal set object that corresponds to the first set object. The second minimum value is both a minimum value supported by a data type (e.g., 1-byte integer) and a minimum value defined to be in the universal set object (e.g., 0 for a universal set of all natural numbers). Similarly, a first maximum value can be normalized based on a second maximum value of the universal set object where the second maximum value is both a maximum value supported by a data type and in the universal set object. Intervals can be normalized, which can involve replacing half-open intervals with equivalent half-closed intervals. Also, a consecutively ordered, uninterrupted, sequence of values of a set object can be normalized. |
