We introduce new trends in applications of equilibrium and nonequilibrium statistical physics, which applies also in many non-traditional areas which are usually called "complexity science". First we explain the critical behavior in the equilibrium case, including the methods of calculations for model systems. After explaining the fundamentals of stochastic processes, we will deal with selected problems of nonequilibrium statistical physics and complex systems: dynamical scaling, cellular automata, random networks, optimization problems. For the 4th and 5th year of the TF study.
