class IStepper

Source: Source/Schola/InferenceUtils/Public/Steppers/StepperInterface.h

Dependencies: IAgent, IPolicy

Interface for stepper implementations.

A stepper manages the observation-action loop by coordinating agents and policies. It collects observations from agents, passes them to a policy for inference, and applies the resulting actions back to the agents.

Subclassed by UPipelinedStepper, USimpleStepper

Public Functions

Symbol	Details
Init	Initialize the stepper with a single agent and policy.
Init	Initialize the stepper with multiple agents and a policy.

Init

inline virtual bool Init(const TScriptInterface<IAgent> &InAgent,
                         const TScriptInterface<IPolicy> &InPolicy)

Initialize the stepper with a single agent and policy.

Convenience method that wraps the agent in an array and calls the multi-agent Init.

Parameters

• InAgent – [in] The agent to use for stepping

• InPolicy – [in] The policy to use for inference

Returns:

true if initialization succeeded, false otherwise

#	Direction	Name	Type	Description
1	—	InAgent	const TScriptInterface< IAgent > &	The agent to use for stepping
2	—	InPolicy	const TScriptInterface< IPolicy > &	The policy to use for inference

Attributes: inline, virtual

Init

virtual bool Init(const TArray<TScriptInterface<IAgent>> &InAgents,
                  const TScriptInterface<IPolicy> &InPolicy) = 0

Initialize the stepper with multiple agents and a policy.

Sets up the stepper to manage multiple agents using a single shared policy. The policy must support batched inference for multiple agents.

Parameters

• InAgents – [in] Array of agents to manage

• InPolicy – [in] The policy to use for inference

Returns:

true if initialization succeeded, false otherwise

#	Direction	Name	Type	Description
1	—	InAgent	const TScriptInterface< IAgent > &	The agent to use for stepping
2	—	InPolicy	const TScriptInterface< IPolicy > &	The policy to use for inference
