Primordial black holes (PBHs) are an important tool in cosmology to probe the<br />
primordial spectrum of small-scale curvature perturbations that reenter the<br />
cosmological horizon during radiation domination epoch. We numerically solve<br />
the evolution of spherically symmetric highly perturbed configurations to<br />
clarify the criteria of PBHs formation using a wide class of curvature profiles<br />
characterized by five parameters. It is shown that formation or non-formation<br />
of PBHs is determined essentialy by only two master parameters.
