Graph theoretical force methods are highly efficient for the generation of sparse and banded null bases and flexibility -matrices, however, these methods require special considerations when the support conditions are indeterminate. These considerationsי with special methods are presented in this paper which lead to efficient utilization of graph theoretical force method for indeterminate support conditions with no substantial decrease in sparsity.
