Resumen:
We present a new probabilistic algorithm to find a finite set ofpoints intersecting the closure of each connected component of therealization of every sign condition over a family of realpolynomials defining regular hypersurfaces that intersecttransversally. This enables us to show a probabilistic procedure tolist all feasible sign conditions over the polynomials. In addition,we extend these results to the case of closed sign conditions overan arbitrary family of real multivariate polynomials.The complexity bounds for these procedures improve the known ones.
