egttools.numerical.numerical_

The numerical module contains optimized functions and classes to simulate evolutionary dynamics in large populations. This module is written in C++.

Functions

calculate_nb_states	Calculates the number of possible states in a discrete simplex.
calculate_state	Converts a discrete population configuration into a unique index.
calculate_strategies_distribution	Calculates the average frequency of each strategy given a stationary distribution.
is_blas_lapack_enabled	Check if EGTtools was compiled with BLAS/LAPACK acceleration.
is_openmp_enabled	Check if EGTtools was compiled with OpenMP support.
replicator_equation	Computes the replicator dynamics gradient for a 2-player game.
replicator_equation_n_player	Computes the replicator dynamics gradient for N-player games.
sample_simplex	Converts a state index into a group composition vector.
sample_simplex_directly	Samples a discrete population state uniformly at random from the simplex.
sample_unit_simplex	Samples a continuous strategy composition uniformly at random from the unit simplex.
vectorized_replicator_equation_n_player	Vectorized computation of replicator dynamics for 3-strategy N-player games.

Classes
