The paper presents algorithms for calculating frequency-dependent rays. Three variants for the parametrization of seismic models are considered: a grid model, a grid model with the boundaries of geological bodies specified on the grid, and a model specified by explicit functions. The paper presents an analysis of frequency-dependent ray tracing algorithms, determines the optimal algorithms for each model parameterization, as well as their comparison with the results of standard ray theory and finite-difference modeling.
