public void setMaxAlternativeSegmentations(int maxAlternativeSegmentations) {
        ensureNotFrozen();
        this.maxAlternativeSegmentations = maxAlternativeSegmentations;
    }
Returns the maximal number of <i>alternative</i> segmentations allowed in addition to the first one found.
Default is 10000. This will prefer to not consider iterations on segments that are far out in the field,
and which starts late in the query.
