I am not familiar with compression issues. The link you provided looks like
intervals, at least it uses the interval notation. It is half-open
intervals: [a,b[, but for integer intervals [a,b[ = [a,b-1].

Originally, intervals were introduced for numeric computations, which
always produce accurate result. The errors are accumulated as precision
loss.

Intervals are widely used in measurements, mathematical statistics and
fuzzy.

I was not aware of an application for compression. Cool, indeed.
