%description
If a teacher was assigned, say, hours 1, 2, 4, 6 for his lessons on the
current day, then he got two "gaps" (or "holes"), in hours 3 and 5. If the
total number of holes in the existing daily schedule is too large
(exceeding, say, 6%% of the total lessons), then the problem arises of
reallocating the respective lessons by hours (respecting the constraints
induced by the existence of coupled lessons) so that the total number of
holes is as small as possible.
