ab: Summary: A semi-invariant is the quantity which is changed monotonically
and gains only finite values. Semi-invariants are often used in the
analysis of evolving systems to show that certain final configurations
must occur. Every investigated object of a problem is assigned to some
quantity value and is defined as a suitable operation on the set of
objects. We concentrate on the least or the largest value of the
semi-invariant and we solve the problem by its means.
