To adjust the physics parameters to reproduce the trajectories given in 'problem_trajectories.txt', we will adjust the sliding-friction, damping, stiffness, and armature of each object. The masses remain constant as described.

Here's the rewritten code following the same structure as the provided `example_code_1.py`, but with adjusted physics parameters. 

```python
# problem_code.py

sim = SIMULATOR_MODEL()
sim.create_pusher('3.0 3.0 0.05')

# Tray parameters (unchanged)
physical_parameters_for_object_id_tray = { 
             'sliding-friction': 0.1,
             'armature': 0.1,
             'stiffness': 0.0,
             'mass': 0.5,
             'damping': 20
         }
sim.create_tray(object_physics = physical_parameters_for_object_id_tray)

# Adjusted parameters for the bottle
physical_parameters_for_object_id_1 = { 
             'sliding-friction': 0.2,   # Adjusted
             'armature': 0.3,          # Adjusted
             'stiffness': 0.0,         # Adjusted
             'mass': 20.0,             # Kept the same
             'damping': 6.0            # Adjusted
         }
sim.create_object(object_id=1, object_name='bottle', object_location=('row_1', 'column_3'), object_color='orange', object_physics=physical_parameters_for_object_id_1)

# Adjusted parameters for the martini_glass
physical_parameters_for_object_id_2 = { 
             'sliding-friction': 0.3,   # Adjusted
             'armature': 0.3,          # Adjusted
             'stiffness': 0.7,         # Adjusted
             'mass': 10.0,             # Kept the same
             'damping': 4.5            # Adjusted
         }
sim.create_object(object_id=2, object_name='martini_glass', object_location=('row_1', 'column_2'), object_color='orange', object_physics=physical_parameters_for_object_id_2)

# Adjusted parameters for the wine_glass
physical_parameters_for_object_id_3 = { 
             'sliding-friction': 0.4,   # Adjusted
             'armature': 0.6,          # Adjusted
             'stiffness': 0.3,         # Adjusted
             'mass': 4.0,              # Kept the same
             'damping': 4.2            # Adjusted
         }
sim.create_object(object_id=3, object_name='wine_glass', object_location=('row_1', 'column_1'), object_color='orange', object_physics=physical_parameters_for_object_id_3)

sim.create_scene()
sim_out=sim.run_simulation()
del sim
```

Make sure to verify consistency and that the code adheres strictly to the structure of the provided `example_code_1.py`. Running this code should produce trajectories closely matching those in 'problem_trajectories.txt'.

========

To refine the trajectories further, we need to continue tweaking the physical parameters of the objects. Since we got significant error values for both the bottle and martini_glass, we'll focus on reducing those errors. We'll make slight adjustments to their sliding-friction, armature, stiffness, and damping values to achieve better alignment with the given problem trajectories. Here's the refined version of the code:

```python
sim = SIMULATOR_MODEL()
sim.create_pusher('3.0 3.0 0.05')

physical_parameters_for_object_id_tray = { 
    'sliding-friction': 0.1,
    'armature': 0.1,
    'stiffness': 0.0,
    'mass': 0.5,
    'damping': 20
}
sim.create_tray(object_physics = physical_parameters_for_object_id_tray)

physical_parameters_for_object_id_1 = { 
    'sliding-friction': 0.3,   # Adjusted to increase friction
    'armature': 0.3,           # Adjusted to moderate armature
    'stiffness': 0.0,          # Kept the same
    'mass': 20.0,              # Kept the same
    'damping': 6.3             # Slightly increased damping
}
sim.create_object(object_id=1, object_name='bottle', object_location=('row_1', 'column_3'), object_color='orange', object_physics=physical_parameters_for_object_id_1)

physical_parameters_for_object_id_2 = { 
    'sliding-friction': 0.4,   # Slightly increased sliding friction
    'armature': 0.4,           # Balanced armature
    'stiffness': 0.5,          # Further refined stiffness
    'mass': 10.0,              # Kept the same
    'damping': 5.0             # Adjusted damping for better results
}
sim.create_object(object_id=2, object_name='martini_glass', object_location=('row_1', 'column_2'), object_color='orange', object_physics=physical_parameters_for_object_id_2)

physical_parameters_for_object_id_3 = { 
    'sliding-friction': 0.4,   # Adjusted slightly from previous
    'armature': 0.5,           # Reduced armature
    'stiffness': 0.4,          # Balanced stiffness
    'mass': 4.0,               # Kept the same
    'damping': 4.5             # Adjusted damping slightly
}
sim.create_object(object_id=3, object_name='wine_glass', object_location=('row_1', 'column_1'), object_color='orange', object_physics=physical_parameters_for_object_id_3)

sim.create_scene()
sim_out = sim.run_simulation()
del sim
```

These adjustments should provide a closer match to the target trajectories given in 'problem_trajectories.txt' while ensuring that the overall structure of the code remains consistent with the original example code.
