The multi-agent resource allocation problem corresponds to the negotiation of <i>m</i> resources among <i>n</i> autonomous agents, in order to maximize a soc...

BibTeX reference

We investigate a first column generation (CG) formulation for the design of failure independent path-protecting (FIPP) <i>p</i> -cycle survivable transport ...

BibTeX reference
