Inconsistency in step Function Signature and Usage

[dxyzx0]

Dear Developers,

I am currently integrating some modules from your codebase, and I've come across an inconsistency that's causing some confusion. The step function in src/train_child.py is defined as follows:

def step(original_action, configs, Problem)
According to the documentation and source code, this function returns 11 values.

However, in annealing_generator.py, the step function is used differently:

reward_, t1, t2, nv1, nc1, nv2, nc2, solved_int1, total_int1, solved_int2, total_int2, obj1, obj2, real_obj1, real_obj2, nv1_origin, nc1_origin, nv2_origin, nc2_origin, e_reward1, e_reward2, primal_dual_integral_1, primal_dual_integral_2 = step(
    action,
    configs,
    Problem,
    instance_id,
    process_id)

Here, it appears that the function is expected to return 23 values.

Could you help clarify the correct usage of the step function? Specifically, are there additional parameters and return values that are not documented, or is there an error in the annealing_generator.py file?

Thank you for your assistance.
