Figure 3. shows the evolution of the tasks performed by each resource and the prices of the time slots after finishing the simulation. This figure shows how the duality gap increases when the projects P4 and P5 arrive to the system. At this moment previous prices did not reflect the new system state (new projects are in the system). After some time, the prices change to adapt themselves to the new system conditions, and the gap decreases again. It can be observed that the new prices are very different from previous prices. This happens especially in resource R1 where prices are very high.
