On the expected payment of mechanisms for task allocation
We study a representative task allocation problem called shortest paths: Let G be a graph in which the edges are owned by self interested agents. The cost of each edge is privatel...

Reliability of Connections in Multilayer Networks under Shared Risk Groups and Costs Constraints
The notion of Shared Risk Resource Groups (SRRG) has been introduced to capture survivability issues when a set of resources may fail simultaneously. Applied to Wavelength Divisio...
