NegMAS CLI

When installing NegMAS through the pip command, you get two command line tool that can be used to aid your development and testing.

This section describes the negmas CLI which provides a unified interface to all negmas commands.

The set of supported commands are:

Command	Meaning
genius-setup	Downloads the genius bridge and updates your settings.
genius	Run a Genius Bridge. This bridge allows you to use GeniusNegotiator agents. Please notice that this command by-default runs in the foreground preventing further input to the terminal.
tournament	Runs a tournament
version	Prints NegMAS version

The commands genius-steup have no parameters and will download genius for later use by the genius command.

Genius Bridge (negmas genius)

The command genius can be used to start a JVM running the Genius platform allowing GeniusNegotiator objects to interact with existing GENIUS agents (Thanks for Tim Baarslag Lead Developer of GENIUS for allowing us to ship it within NegMAS).

You can get help on this tool by running:

$ negmas genius --help

This tool supports the following optional arguments:

Argument	Meaning
-p/–path TEXT	Path to genius-8.0.4.jar with embedded NegLoader [OPTIONAL]
-r/–port INTEGER	Port to run the NegLoader on. Pass 0 for the default value [OPTIONAL]
–force/–no-force	Force trial even if an earlier instance exists [OPTIONAL]
–help	Show help message and exit.

Tournament Command (negmas tournament)

The Tournament command (tournament) allows you to run a tournament between different agents in some world and compare their relative performance. The tool is general enough to support several world types.

You can get help on this tool by running:

$ negmas tournament --help

The tournament command has a set of sub-commands for creating, running, and combining tournament results as follows:

Command	Action
combine	Finds winners of an arbitrary set of tournaments
create	Creates a tournament
run	Runs/continues a tournament
winners	Finds winners of a tournament or a set of tournaments sharing

Creating a tournament

These are the optional arguments of this tool:

–log-negs / –no-neg-logs	Log all negotiations. Only effective if –debug is given [default: False]
–compact / –debug	If True, effort is exerted to reduce the memory footprint whichincludes reducing logs dramatically. [default: True]
–raise-exceptions / –ignore-exceptions	Whether to ignore agent exceptions [default: True]
–path TEXT	A path to be added to PYTHONPATH in which all competitors are stored. You can path a : separated list of paths on linux/mac and a ; separated list in windows
–java-interop-class TEXT	The full name of a class that is used to represent Java agents to the python envirnment. It is only used if jcompetitors was passed
–config-generator TEXT	The full path to a configuration generator function that is used to generate all configs for the tournament. MUST be specified
–world-generator TEXT	The full path to a world generator function that is used to generate all worlds (given the assigned configs for the tournament. MUST be specified
–assigner TEXT	The full path to an assigner function that assigns competitors to different configurations
–scorer TEXT	The full path to a scoring function
–cw INTEGER	Number of competitors to run at every world simulation. It must either be left at default or be a number > 1 and < the number of competitors passed using –competitors
–config FILE	Read configuration from FILE.

Running a tournament

After creating a tournament using the tournament create command, it can be run using the tournament run command. The parameters for this command are:

Argument	Meaning
-n, –name TEXT	The name of the tournament. When invoked after create, there is no need to pass it
-l, –log DIRECTORY	Default location to save logs [default: ~/negmas/logs/tournaments]
–verbosity INTEGER	verbosity level (from 0 == silent to 1 == world progress) [default: 1]
–parallel / –serial	Run a parallel/serial tournament on a single machine [default: True]

–compact / –debug	If True, effort is exerted to reduce the memory footprint whichincludes reducing logs dramatically. [default: True]
–path TEXT	A path to be added to PYTHONPATH in which all competitors are stored. You can path a : separated list of paths on linux/mac and a ; separated list in windows
–metric TEXT	The statistical metric used for choosing the winners. Possibilities are mean, median, std, var, sum [default: mean]
–config FILE	Read configuration from FILE.

Upon completion, a complete log and several statistics are saved in a new folder under the log folder location specified by the --log argument (default is negmas/logs/tournaments under the HOME directory). To avoid over-writing earlier results, a new folder will be created for each run named by the current date and time. The folder will contain the following files:

File/Folder Name	Format	Content
configs	FOLDER	Contains one json file for each world run tried during the tournament. You can re-run this world using run_world function in the tournament module.
params.json	JSON	The parameters used to create this tournament

assigned_configs.json	JSON	The configurations used after assigning factories to managers
scores.csv	CSV	Scores of every agent in every world
total_scores.csv	CSV	Scores of every agent type averaged over all runs
winners.csv	CSV	Winner types and their average scores
ttest.csv	CSV	Results of a factorial TTEST comparing the performance of all agent types

Other than these files, a folder with the same number as the corresponding config file in the configs folder, keeps full statistics/log of every world but only if –debug is specified (see the World Runner section for the contents of this folder.

Negotiate CLI

When installing NegMAS through the pip command, you get two command line tool that can be used to aid your development and testing.

This section describes the negotiate CLI which provides a simple way for running negotiations, plotting them, saving their statistics, etc.

You can find out about all the available options by running
