A feasible solution x = [([x.sub.B], [x.sub.N]).sup.t] to (4.1) obtained by setting [x.sub.B] = [B.sup.-1]b, [x.sub.N] = 0 is called a neutrosophic basic feasible solution ([N.sub.BFS]).
To solve any N LP-problem by simplex method, the existence of an initial basic feasible solution is always assumed.
