iocrn_stepper

RL4CRN.agent2env_interface.iocrn_stepper

Concrete stepper for IO-CRN environments.

This stepper applies an action by adding a reaction to the environment state via state.add_reaction(action) and then calling state.compile().

Limitations

Parameter-setting is not implemented. If the state reports unknown parameters (state.num_unknown_params > 0), step raises NotImplementedError.

Assumptions about state :

• has attribute num_unknown_params: int
• provides methods add_reaction(action) and compile()

IOCRNStepper

Bases: AbstractStepper

Stepper that adds a reaction to the CRN state and recompiles it.

The action is applied through state.add_reaction(action). Afterward, state.compile() is called to finalize the updated state.

RAISES	DESCRIPTION
NotImplementedError	If state.num_unknown_params > 0.

step(state, action)

Apply action to state by adding a reaction and compiling.

PARAMETER	DESCRIPTION
state	Environment state to be modified (see module docstring for the required interface).
action	Reaction/action object passed to state.add_reaction(action).

RAISES	DESCRIPTION
NotImplementedError	If the state contains unknown parameters and would require setting them (state.num_unknown_params > 0).
