— In this paper we provide a survey of three classes of combinatorial optimization problems that arise in communication network analysis. These problems, referred to as QoS (Qual...
We obtain the following results related to dynamic versions of the shortest-paths problem: (i) Reductions that show that the incremental and decremental singlesource shortest-paths...
A celebrated theorem of Savitch [Sav70] states that NSPACE(S) ⊆ DSPACE(S2 ). In particular, Savitch gave a deterministic algorithm to solve ST-CONNECTIVITY (an NL-complete probl...
This paper describes a GRASP with path-relinking heuristic for the quadratic assignment problem. GRASP is a multi-start procedure, where different points in the search space are p...

In this work, the problem of open faults affecting the interconnections of SC circuits composed by data-path and control is analyzed. In particular, it is shown that, in case open...
