Nesting Tasks Dataset for 2D-Nesting Efficiency Estimation

<p>Nesting efficiency dataset</p> <p>This is the raw dataset associated with the paper &ldquo;Graph Neural Networks Comparison for 2D-Nesting Efficiency Estimation&rdquo;, by C.Lallier, L. V&eacute;zard, B. Pinaud and G. Blin,&nbsp;2022. Consisting of 100,000 nesting tasks.</p> <p><strong>Usage:</strong></p> <p>The files are: <em>tasks.gz,&nbsp;parts.gz,&nbsp;constraints.gz, </em>and<em>&nbsp;shapes.gz</em>.&nbsp;They&nbsp;are in&nbsp;PICKLE file format&nbsp;version 5 with a gzip compression. Example to load a file :</p> <pre><code class="language-python">import pandas as pd tasks = pd.read_pickle('tasks.gz')</code></pre> <p>&nbsp;</p> <p><strong>Description:</strong></p> <p><em>Tasks.gz</em> file contains nestings high-level descriptors.
