TOIDecMDPDiscrete::TOIDecMDPDiscrete ( const std::string &  name = "received unspec. by TOI-DecMDPDiscrete",
const std::string &  descr = "received unspec. by TOI-DecMDPDiscrete",

(default) Constructor

TOIDecMDPDiscrete::~TOIDecMDPDiscrete ( )
virtual

Destructor.

Member Function Documentation

void TOIDecMDPDiscrete::CreateStateObservations ( )

This function creates the 'state observations'.

I.e., for each agent the same number of observations as local states is created. The observation probabilities are set such that in a particular state the corresponding observation is received with certainty.

bool TOIDecMDPDiscrete::SetInitialized ( bool  b)
virtual

Sets _m_initialized to b.

When setting to true, a verification of member elements is performed. (i.e. a check whether all vectors have the correct size and non-zero entries)

Reimplemented from TOIDecPOMDPDiscrete.
