 ### Other remarks
-- The `XML100` benchmark set is not listed in `list_names` and cannot be downloaded through this package. You can download these instances directly from [CVRPLIB](http://vrp.atd-lab.inf.puc-rio.br/index.php/en/).
 - In the literature, some instances use rounding conventions different from what is specified in the instance. For example, X instance set proposed by [Uchoa et al. (2017)](http://vrp.atd-lab.inf.puc-rio.br/index.php/en/new-instances) assumes that the distances are rounded to the nearest integer. When you use the `vrplib` package to read this instance, it will return non-rounded Euclidean distances because the instance specifies the `EUC_2D` edge weight type which implies no rounding. To adhere to the convention used in the literature, you can manually round the distances matrix.
 - For large instances (>5000 customers) it's recommended to set the `compute_edge_weights` argument to `False` in `read_instance`.
