Algorithms for COOPERATIVE DS: Leader Election in the MPS model

Algorithms for COOPERATIVE DS: Leader Election in the MPS model. Leader Election (LE) problem. In a DS, it is often needed to designate a single processor (i.e., a leader ) as the coordinator of some forthcoming task (e.g., find a spanning tree using the leader as the root)
