Normally, capacity checks check for each group if each node can be evacuated. However, to support the "independent groups" option in hspace computations, two things have to be done for groups initially not redundant. - No instance are allocated on those groups, and - they must be ignored in global N+1 checks during the computation. The latter is achieved by this algorithmic parameter.
