Constructor & Destructor Documentation

RewardModelMappingSparse::RewardModelMappingSparse	(	size_t	nrS = 1,
		size_t	nrJA = 1,
		const std::string &	s_str = "s",
		const std::string &	ja_str = "ja"
	)

default Constructor nrS - number of states nrJA - number of joint actions s_str - how to call a state (For example you can use this class to create a mapping from observation histories and ja's to reals.

Then this argument could be "joh") ja_str - idem for the joint actions

Member Function Documentation

virtual RewardModelMappingSparse* RewardModelMappingSparse::Clone ( ) const

inlinevirtual

Returns a pointer to a copy of this class.

Implements RewardModelDiscreteInterface.

References RewardModelMappingSparse().

double RewardModelMappingSparse::Get ( Index  s_i, Index  ja_i  ) const

inlinevirtual

Returns R(s,ja)

Implements RewardModelDiscreteInterface.

References _m_R.

Referenced by SoftPrint().

void RewardModelMappingSparse::Set ( Index  s_i, Index  ja_i, double  rew  )

inlinevirtual

Sets R(s_i,ja_i)

Index ja_i, Index s_i, are indices of the state and taken joint action. r is the reward. The order of events is s, ja, so is the arg. list.

Implements RewardModelDiscreteInterface.

References _m_R, and Globals::REWARD_PRECISION.

string RewardModelMappingSparse::SoftPrint ( ) const

virtual

Prints a description of this to a string.

Implements RewardModelDiscreteInterface.
