Extrakardiale digitaliswirkungen,he pebbles form a connected subgraph (connectivity), or interconnect a constant number of stationary nodes (Steiner tree). These problems model the minimization of the total time required to reconfigure a robot swarm to achieve a proximity (e.g., radio) network with these connectivity properties. Ou

This problem can be formulated either with specific costs incurred for choosing to open each depot, or with an uppe

The goal is to maximize the number of demands satisfied, where each demand is an interval with a starting and ending time, and a certain resource requirement. This problem arises naturally in many scenarios, e.g., the
