DARP instances
-
20 pr instances (Cordeau and Laporte, 2003)
-
a and b instances (Cordeau, 2006)
- Instance are available here
- H-DARP instances
- MD-H-DARP instances
- Same as H-DARP instances except no single vehicle depot at (0,0), but four vehicle depots at (-5,-5), (5,5), (-5,5) and (5,-5). For each instance, the available vehicles are assigned to the four depots as follows: the first vehicle to the first depot, the second vehicle to the second depot, ..., the fifth vehicle to the first depot, and so on.

- Unary epsilon indicator
- The reference set consists of the set of non-dominated solutions obtained over all six variants of the algorithm together
