Diffusion Limited Aggregation

Many attractive images and life-like structures can be generated using models of physical processes from areas of chemistry and physics. One such example is diffusion limited aggregation or DLA which describes, among other things, the diffusion and aggregation of zinc ions in an electrolytic solution onto electrodes. "Diffusion" because the particles forming the structure wander around randomly before attaching themselves ("Aggregating") to the structure. "Diffusion-limited" because the particles are considered to be in low concentrations so they don’t come in contact with each other and the structure grows one particle at a time rather then by chunks of particles. Other examples can be found in coral growth, the path taken by lightning, coalescing of dust or smoke particles, and the growth of some crystals. Perhaps the first serious study of such processes was made by Witten, T.A. and Sander, L. M. and published by them in 1981.

To reproduce the experiments in notebooks, we suggest using the notebook ./experiment.ipynb and tuning the parameters inside the source code ./DLA.c for different experiments. For more details, please follow the section below.

Guidelines

1. Upload all folders and files of this repository into Google Drive.
2. Open the notebook experiment.ipynb.
3. At the second cell where you may see the command:

   %cd "/content/drive/MyDrive/<path to uploaded repo>"
   

   Change the <path to uploaded repo> into the path of the folder that contains your uploaded files and folders in Google Drive.
4. Run sequentially the notebook.
5. Results are shown at the last cell and saved to the folder ./output.
