In this paper, we consider variants of the traveling salesman problem with precedence constraints. We characterize hard input instances for Christofides' algorithm and Hoogeve...
The spectral properties of the incidence matrix of the communication graph are exploited to provide solutions to two multiagent control problems. In particular, we consider the pr...
A bisection of a graph with n vertices is a partition of its vertices into two sets, each of size n/2. The bisection cost is the number of edges connecting the two sets. The proble...
The paper elucidates two views (models) of algorithmic problem solving. The first one is static; it is based on the identification of several principal dimensions of algorithmic p...
Continuous-variable simulation optimization problems are those optimization problems where the objective function is computed through stochastic simulation and the decision variab...
