Dear Miplib-Team, I made a mistake in the bibtex references field (Submission at 2017-02-17 16:53). ​The year of the technical report should be 2017 and not 2016. ​ @INPROCEEDINGS{cVRPsTWOR16, author = {Hungerl\"ander, P. and Maier, K. and Pöcher, J. and Rendl, A. and Truden, C.}, booktitle={Operations Research Proceedings 2016}, title={Solving an {O}n-line {C}apacitated {V}ehicle {R}outing {P}roblem with {S}tructured {T}ime {W}indows}, note = {accepted}, year=2016} @techreport{huma16, author = {Hungerl\"ander, P. and Maier, K. and Pöcher, J. and Rendl, A. and Truden, C.}, title={Solving an {O}n-line {C}apacitated {V}ehicle {R}outing {P}roblem with {S}tructured {T}ime {W}indows}, address = {Alpen-Adria Universität Klagenfurt, Mathematics, Optimization Group}, number = {TR-AAUK-M-O-17-02-13}, year={2017} } It seems that I am not able to change it myself. So could you please change it for me? Thanks, Kerstin Maier
