Builds a group of ProblemEnv instances from a factory callable.

Fields:

• env_thunk ( Callable[], ProblemEnv)
• num_envs ( _int_)
• dataset_name ( str, default: 'problems')

make_envs()

Create num_envs ProblemEnv instances using the factory callable.

Returns: Sequence[ Env]

compute_group_rewards( trajectory_group, env_group)

Return zero group rewards (all rewards come from per-step scoring).

Parameters:

• trajectory_group ( _list[ Trajectory]_)
• env_group ( _Sequence[ Env]_)

Returns: list[tuple[float, Metrics]]
