MS91-WEIGHT-LIMIT-RANGE : FLAG

MS91-WEIGHT-LIMIT-RANGE is a flag or parameter.
New option-sets, when constructed, will be accepted if their weights lie
in the range [current weight limit, current weight limit + MS91-WEIGHT-LIMIT-RANGE].
Hence increasing this value means that more option-sets will be acceptable during
the creation stage. If this range is very small, there is a risk that no option
sets at all will be accepted and the search will waste time recreating these sets
with a higher current weight limit. If it is too large, then there is a risk that
high-weighted sets will be considered before lower-weighted ones.
Note: option sets of weight INFINITY will never be accepted, no matter what.
MS91-WEIGHT-LIMIT-RANGE takes values of type INTEGER+-OR-INFINITY.
It belongs to subjects MS91-7 MS91-6 .
Its default value is 1
Its current value is 1.
