class Logger:

Constructor: Logger(directory_path, assemblage, model_type, save_images)

Logger objects track market states throughout experiments for future analysis.

Method	`__init__`	Instantiates a Logger object.
Method	`get_pot_distributions`	Get distributions of purchased items in marketplace.
Method	`initialize_results_logger`	Sets up the logger with field names and heading information.
Method	`log`	Undocumented
Method	`log_buyers`	Log buyers and their states at a particular timestep.
Method	`log_communities_matrix`	Log communities and their states at a particular timestep.
Method	`log_scale_free`	Logs statistics about the market at a particular timestep in a scale free experiment.
Method	`log_small_world`	Logs statistics about the market at a particular timestep in a small world experiment.
Method	`log_swi`	Log the current small world index.

def __init__(self, directory_path, assemblage, model_type='small_world', save_images=True): ¶

Instantiates a Logger object.

Parameters
directory_path	path of directory to store results files
assemblage	list of items for sale in marketplace
model_type	scale free or small world (default: small world)
save_images	save static images of graphs throughout training (default: True)

def get_pot_distributions(self, graph): ¶

Get distributions of purchased items in marketplace.

Parameters
graph	graph representing the current market state
Returns
distribution in dictionary form of purchased items

def initialize_results_logger(self, graph, all_buyers_in_market): ¶

Sets up the logger with field names and heading information.

Parameters
graph	graph representing the current market state

def log(self, graph, epoch, timestep, num_rewires, all_buyers_in_market): ¶

Undocumented

def log_buyers(self, graph, timestamp): ¶

Log buyers and their states at a particular timestep.

Parameters
graph	graph representing the current market state
timestamp	a list containing the epoch and timestep

all_buyers_in_market	list of all buyers in market

def log_small_world(self, small_world_graph, timestamp, num_rewires): ¶

Logs statistics about the market at a particular timestep in a small world experiment.

Parameters
small_world_graph	graph representing current market state
timestamp	a list containing the epoch and timestep
num_rewires	number of nodes that were rewired this timestep

def log_swi(self, graph, epoch, timestep): ¶

Log the current small world index.

Parameters
graph	graph representing the current market state
epoch	current epoch
timestep	current timestep
