egttools.utils

This python module contains some utility functions to find saddle points and plot gradients in 2 player, 2 strategy games.

Functions

calculate_nb_unique_combinations	Calculates the number of unique combinations given the required number of elements of each group, which should be given in List format in the slots_per_bin parameter.
calculate_stationary_distribution	Calculates stationary distribution from a transition matrix of Markov chain.
calculate_stationary_distribution_non_hermitian	Calculates stationary distribution from a transition matrix of Markov chain which is not hermitian.
combine	Outputs a generator that will generate an ordered list with the possible combinations of values with length.
eigvals	Compute eigenvalues from an ordinary or generalized eigenvalue problem.
find_saddle_type_and_gradient_direction	Finds whether a saddle point is stable or not.
get_payoff_function	Returns a function which gives the payoff of strategy i against strategy j.
schur	Compute Schur decomposition of a matrix.
transform_payoffs_to_pairwise	This function transform a payoff matrix in full format to a pairwise format.
warn	Issue a warning, or maybe ignore it or raise an exception.

Classes

AbstractGame	Abstract class which must be implemented by any new game.
csc_matrix	Compressed Sparse Column matrix
csr_matrix	Compressed Sparse Row matrix
