Hardware / software:All computational experiments have been carried out on a computing cluster (Compute Canada) composed by Intel Xeon X5650 Westmere processors with 2,67 GHz and 512 GB of RAM running Scientific Linux release 6.3. All algorithms were coded in ANSI C 99 and compiled with GCC version 5.4.0, with flags -Ofast and solver GUROBI version 8.0.1 (Gurobi Optimization, 2016).
