Implements the DecentralizingAgent which creates ony buy and one sell controller for each time-step and relinquishes control of negotiations to buy/sell the required number of items of its input/output product.

class scml.scml2020.agents.moving.MovingRangeAgent(*args, price_weight=0.7, utility_threshold=0.9, time_threshold=0.9, time_horizon=0.1, min_price_margin=0.5, max_price_margin=0.5, **kwargs)

Bases: scml.scml2020.components.MovingRangeNegotiationManager, scml.scml2020.components.trading.PredictionBasedTradingStrategy, scml.scml2020.components.SupplyDrivenProductionStrategy, scml.scml2020.world.SCML2020Agent

My negotiation strategy

Parameters:

• price_weight – The relative importance of price in the utility calculation.

• utility_threshold – The fraction of maximum utility above which all offers will be accepted.

• time_threshold – The fraction of the negotiation time after which any valid offers will be accepted.

• time_range – The time-range for each controller as a fraction of the number of simulation steps

Hooks Into:

• init

• step

Remarks:

• Attributes section describes the attributes that can be used to construct the component (passed to its __init__ method).

• Provides section describes the attributes (methods, properties, data-members) made available by this component directly. Note that everything provided by the bases of this components are also available to the agent (Check the Bases section above for all the bases of this component).

• Requires section describes any requirements from the agent using this component. It defines a set of methods or properties/data-members that must exist in the agent that uses this component. These requirement are usually implemented as abstract methods in the component

• Abstract Objects Layer section describes abstract methods that MUST be implemented by any descendant of this component.

• Hooks Into section describes the methods this component overrides calling super () which allows other components to hook into the same method (by overriding it). Usually callbacks starting with on_ are hooked into this way.

• Overrides section describes the methods this component overrides without calling super effectively disallowing any other components after it in the MRO to call this method. Usually methods that do some action (i.e. not starting with on_) are overridden this way.

Bases: scml.scml2020.components.prediction.MarketAwareTradePredictionStrategy, MovingRangeAgent

Predicts an amount based on publicly available market information. Falls back to fixed prediction if no information is available
