                                PWLDynamics

Class of objects that represent the dynamics of a specific state/belief feature in the simulation

Instance Methods

[hide private]

__init__(self, args=None)

source code

dict

extractTable(self, entity, action)
Helper function that extracts the context used in instantiating dynamics

source code

PWLDynamics

instantiate(self, entity, action)
Returns a new PWLDynamics instance that has been specialized to apply to only the specified entity in response to the specified instantiated action.

source code

Distribution(KeyedMatrix)

instantiateAndApply(self, state, entity=None, action=None, table={}, tree=None)
Performs both instantiate and apply in a single call, but does a minimal instantiation, by ignoring branches that are irrelevant in the given state source code

ProbabilityTree

getTree(self)
Returns: the decision tree for this dynamics object

source code

Distribution(KeyedMatrix)

apply(self, state, debug=0)
Applies this dynamics function to the given state

source code

merge(self, other)
Merges the new dynamics into this one by calling KeyedMatrix.merge on the leaves of the decision trees

source code

renameEntity(self, old, new, tree=None)

source code

__add__(self, other)

source code

__sub__(self, other)

source code

__xml__(self)

source code

parse(self, element)

source code

__str__(self)

source code

Inherited from arbitraryDynamics.BaseDynamics: getIncrement, invert, reset

Instance Variables

[hide private]

str→bool

effects
table of roles affected, containing keys 'actor','object','other'.

Method Details

[hide private]

init(self, args=None)
(Constructor)

source code

Overrides: arbitraryDynamics.BaseDynamics.__init__

instantiate(self, entity, action)

source code

Returns a new PWLDynamics instance that has been specialized to apply to only the specified entity in response to the specified instantiated action. This produces a more compact decision tree where branches irrelevant to the given entity and action have been pruned away.

Parameters:
