class scml.scml2020.components.signing.SignAll

Signs all contracts no matter what.

Overrides:

• sign_all_contracts

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.

class scml.scml2020.components.signing.SignAllPossible

Signs all contracts that can in principle be honored. The only check made by this strategy is that for sell contracts there is enough production capacity

class scml.scml2020.components.signing.KeepOnlyGoodPrices(*args, buying_margin=0.5, selling_margin=0.5, **kwargs)

Signs all contracts that have good prices

Overrides:

• sign_all_contracts

- buying_margin

The margin from the catalog price to allow for buying. The agent will never buy at a price higher than the catalog price by more than this margin (relative to catalog price).

- selling_margin

The margin from the catalog price to allow for selling. The agent will never sell at a price lower than the catalog price by more than this margin (relative to catalog price).
