Class OSTNURandomGenerator

java.lang.Object
it.univr.di.cstnu.util.OSTNURandomGenerator
public class OSTNURandomGenerator extends Object
Allows one to build random OSTNU instances specifying:
  • number of wanted DC/NOT DC instances
And the following parameters that characterize each generated instance:
  • number nodes
  • number of contingent nodes
  • number of oracles
  • max weight for each edge
  • max weight for each contingent link (upper value)
  • max in-degree for each node
  • max out-degree for each node
  • probability to have an edge between any pair of nodes

The class generates the wanted instances, building each one randomly and then DC checking it for stating its DC property.
