Hello Nivedha,

The tabulate file is missing from the project. Kindly upload it.

Thanks, Aditya

I am facing an issue in code of main.py line 139
population = gen.generate_pop(box_params, NUM_OF_INDIVIDUALS, ROTATIONS)
AttributeError: 'int' object has no attribute 'generate_pop'

Hi,

I'm interested in your 3d bin packing algorithm.
Want to know the efficiency of it , and maybe we can discuss adding some features to it.
Is there a way we can talk maybe via email?

Thanks!

Hi Nivedha,
I keep getting errors. It says "AttributeError: 'int' object has no attribute 'generate_pop'" in line 139. I wonder if you can help me fix these errors?

thanks

Hi Mr. Ramesh!

I've been reading your coding recently. When I read to the mutation part, it has something to do with the rotation. I wonder will this cause some unwanted result that user might don't want the rotation.

Here is the code

def mutate(offsprings, pm1, pm2,rotation=6):
    for child in offsprings.values():
        order = child['order']
        rotate = child['rotate']

        # ...

        # Second level of mutation
        for i in range(len(rotate)):
            if random.uniform(0, 1) <= pm2:
                rotate[i] = random.randint(0, rotation)   # This is what I wondered.

    return offsprings

If user only want the box rotate on z-index, or rather only can swap the length and width. Will this cause the box can rotate on length and height?

Please explain the attributes of the dataset used in this project.

What parameters are used?
