In this article we perform a computational study of Polyrakis algorithmspresented in [12,13]. These algorithms are used for the determination of thevector sublattice and the minimal lattice-subspace generated by a finite set ofpositive vectors of R^k. The study demonstrates that our findings can be veryuseful in the field of Economics, especially in completion by options ofsecurity markets and portfolio insurance.
