INRC-II 8weeks Data

This article deals with the nurse scheduling problem as described in the context of the international
competition INRC–II.The experimental tests focus on a benchmark of twenty instances published during the INRC–II.The instances describe the constraints for the schedule of 30 to 120 nurses over 4 and 8 weeks horizon. Table below shows the result obtained by my developping solver.
