The solution space of the rectangular linear system Ax=b, subject to x≥0,
is called a polytope. An attempt is made to provide a deeper geometric insight, with
numerical examples, into the condensed paper by Lord, et al. [1], that presents an algorithm to
compute a center of a polytope. The algorithm is readily adopted for either sequential or
parallel computer implementation. The computed center provides an initial feasible solution
(interior point) of a linear programming problem.
