By using the Monte Carlo method, a numerical study has been conducted to calculate the current-voltage characteristics of a high-temperature superconductor with intrinsic pinning sites and the additional ones in the form of antidots in different magnetic fields. Varioustypes of antidot distribution among the sample such as a random distribution, triangular and square lattice and their conformal transformations, have been considered. Descending critical current density dependencies on the magnetic field for different samples have been acquired. Averaged vortex configurations of samples for different antidot distributions at the same magnetic field and transport current have been acquired. The most effective antidot distribution has been determined.
