Clarification on F-n135-k7 #18

Closed mrprajesh closed 2 years ago

mrprajesh commented 2 years ago

Dear @EduardoQueiroga Could you clarify if coordinate distances for instance InstancesRounded/F-n135-k7.vrp should be truncated or rounded? The rules document mentions the below.

All 129 instances from the literature listed for Phase One use EUC 2D distances (but CMT4, CMT5, tai385, and Golden9-20 instances do not follow the TSPLIB95 convention of rounding to the nearest integer).

Kindly clarify.

PS: We should update the README.md. Currently, at two places it points to the older rules document (August 26, 2020).

Dear @mrprajesh

For this instance, the convention is to round the distance to the nearest integer (as for all the instances in the folder InstancesRounded). README.md has been updated.

Best regards

As all the other instances in that folder had integer coordinates, I was a little puzzled about this. Thanks a lot, @EduardoQueiroga for clarifying.

Kind regards, Rajesh
