Public Functions

MountainCar(const RESTApiServerWrapper &api_server)¶

MountainCar. Constructor. Creates an environment.

Parameters:

version – The version of the environment
gym_namespace – The boost::python open-ai gym namespace
do_create – If true it calls make

MountainCar(const RESTApiServerWrapper &api_server, const uint_t cidx)¶: Constructor. Protected so that applications cannot explicitly instantiate copies.

MountainCar(const MountainCar &other)¶: copy ctor

~MountainCar() = default¶: ~MountainCar. Destructor.

virtual void make(const std::string &version, const std::unordered_map<std::string, std::any>&) final override¶: make. Build the environment

virtual time_step_type step(const action_type &action) final override¶: step

MountainCar make_copy(uint_t cidx) const¶: Create a new copy of the environment with the given copy index.

inline uint_t n_actions() const noexcept¶: n_actions. Returns the number of actions

Public Static Attributes

static const std::string name = "MountainCar"¶: name

static const std::string URI = "/gymnasium/mountain-car-env"¶: The URI for accessing the environment.

Protected Functions

virtual time_step_type create_time_step_from_response_(const nlohmann::json &response) const final override¶: Handle the reset response from the environment server.
