======== Overview

ANAC Supply Chain Management League Platform

Overview

This repository is the official platform for running ANAC Supply Chain Management Leagues. It will contain a package called scmlXXXX for the competition run in year XXXX. For example scml2019 will contain all files related to the 2019's version of the competition.

Installation

::

pip install scml

You can also install the in-development version with::

pip install https://github.com/yasserfarouk/scml/archive/master.zip

We only support python 3.10 and 3.11. The reason python 3.12 is not yet supported is that stable_baselines3 is not supporting it yet.

Documentation

https://scml.readthedocs.io

Development

To run the all tests run::

tox

Note, to combine the coverage data from all the tox environments run:

.. list-table:: :widths: 10 90 :stub-columns: 1

- - Windows
  - ::

        set PYTEST_ADDOPTS=--cov-append
        tox

- - Other

0.6.2 (2023.11.27)

• upgrading CI to python 3.12
• importing observations
• dropping support for python < 3.10
• Completing first draft of the RL environment

0.6.1 (2023.7.9)

• Moving scml.scml2020.utils to scml.utils (to avoid a circular import in rl/factory)
• This is an initial effort to have RL work for scml. Currently we are disabling the extra checks on observation and world construction because they lead to failures. This needs to be rectified later.
• Added the concept of a WorldFactory to generate worlds with predefined characteristics from the point of view of the learning agent.
• Now environments, action managers, and observation managers all receive WorldFactory objects and automatically check for compatibility.

0.6.0 (2023.7.9)

• Upgrading to be compatible with NegMAS 0.10.0
• Adding step_with() to oneshot allowing for single counter-offer set stepping of the simulation (to be used to expose the simulation as RL and MARL environments later).
• Adding current_negotiation_details to OneShotAWI to get details of running negotiation
• Adding managed sales, supplies, total_sales, total_supplies, needed_sales, and needed_supplies to the OneShotAWI
• Extending OneShotState returned from awi.state and awi.default_state_encoder(mechanism_states) to expose more information about the simulation

0.5.6 (2023.3.8)

• Upgrading to be compatible with NegMAS 0.9.8
• Updating notebooks for 2023 release
• Adding 2023 specific classes and utility functions
• Supporting most recent negmas version on Github
• Adding the ability to use raw collusion scores In the collusion track, it is now possible to control how much does the raw collusion score affect the final score relative to the difference between raw collusion score and standard score.
• more reobust renaming when reveal-names is set

0.5.5 (2022.5.18)

• bugfix in anac2022_* methods: Score reporting was not accurate because of a change in naming convention in negmas.
• adding agent-processes to SCML2022World.generate
• Adding SCML2022World which is just an alias for SCML2021World
• bugfix #96 Partial List of Agent Scores: Also discussion $94
  • Incorrect agent types and mysterious agents appearing in the scores list.
  • Inaccurate placement of agents in the simulation
• disabling tests taking too long on CI
• commenting members of Profile, Contract in oneshot

0.5.4 (2022.5.15)

• Disabling adapter testing. Adapting SCML2020 and OneShot agents is too much effort and is not reallly that useful. We will eventually remove support for that.
• Improving control over oneshot world generation. SCML2020OneShotWorld.generat() method now is more consistent in the way it creates agents.
• Adding wide_price_range to control the unit-price range

0.5.3 (2022.5.14)

• randomizing starting agents in oneshot
• improving AWI typing in oneshot
• Resetting agents before making negotiations
• • before_step() was also resetting agents in oneshot. This meant that all
• negotiators that were created in _make_negotiations() were deleted in
• reset().
• • Now we call reset() before making negotaitions and before_step() after
• that.
• • This guarantees that the agent has access to its negotiators in
• before_step() as in 2020.
• Adding new collusion evaluation
• Goal: Disentangle the quality of the collusion strategy and the standard
• strategy.
• Method: Each agent now has 3 factories in collusion. We run four
• simulations:
• • s0: The agent controls all of the three factories
• • s1-s3: The agent controls one of them
• The final score of the agent is its score in s0 minus the average score
• it got in s1-s3
• Avoid calling counter_all before first_offers
• github actions update
• improved testing of sync behavior
• Confirming that OneShotSync gets all offers every counter_all() call and upper limiting the difference in negotiation speeds based on Jackson's code
