Abstract
For every basic feasible solution x ∉ χ we have by Lemma 1 a feasible basis B. for every feasible basis B with index set I we have the reduced system
where \( \bar b = B^{ - 1} b \). Hence a basic feasible solution x ∈ χ is defined by
where pℓ is the position number of the variable ℓ ∈ I. if \( I = \left\{ {k_1 , \ldots k_m } \right\} \), we can write equivalently
