Member Function Documentation

◆ parseMDP()

MDPVals AIToolbox::CassandraParser::parseMDP ( std::istream & input )

This function parses the input following Cassandra's rules.

This function only parses for information regarding an MDP, so number of states, number of actions, discount and transition/reward functions.

Any problems during parsing result in an std::runtime_error.

The output is returned as a set of values which if needed can be used to build an MDP::Model.

No checks are done here regarding the consistency of the read data (transition probabilities, etc).

Parameters

input The input stream to parse.

Returns: A tuple containing S, A, T, R, and discount of the parsed MDP.

◆ parsePOMDP()

POMDPVals AIToolbox::CassandraParser::parsePOMDP ( std::istream & input )
