The Monte Carlo method with the use of the Wang–Landau algorithm is applied to study the lattice models of free polymer chains and 6-arm polymer stars. The ratio of self-avoiding walks among semi-phantom walks for the chains of length $N\leq 300$ and the stars with the total number $N\leq 720$ of segments is determined. The distribution over the number of monomers' contacts for chains and stars with the number $N=30, 72, 120$ of segments is obtained. Based on this distribution, the temperature dependences are found for the internal energy, the heat capacity, and the entropy.
Keywords: polymer star; Wang-Landau algorithm.
