Some products cannot be stored in shelves.\n- The loction of the incoming **orders** (groups of **items** of different **products**) are optimized so as to **minimise used surface and access time**.\n\n## Algorithm\n\nThe solutions of the the problem is found through a local search algorithm, where several randomly generated initial solutions are optimized in parallel. The cost functions are normalized based on randomly generated solutions and scalarized using a weighted geometric mean. One may set the weights to prioritize one objective over another.\n\n## Environment / Setup\n\n```bash\ngit clone https://github.com/rcote98/logStoreOpt.git    # clone the repo\ncd logStoreOpt                                          # move in the folder\npython3 -m venv logStoreOpt_env                         # create virtualenv\nsource logStoreOpt_env/bin/activate                     # activate it\npip install -r requirements.txt                         # install dependencies\npython3 example.py                                      # run the example code\n```\n","funding_links":[],"categories":[],"sub_categories":[],"project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Frcoteru%2Flogstoreopt","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Frcoteru%2Flogstoreopt","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Frcoteru%2Flogstoreopt/lists"}
