For axis-parallel segment intersection graphs, we design an algorithm that finds a maximal independent set in .(.) rounds, where . is the diameter of the graph. We further show that this independent set is a .-approximation. The

K. N. Trohidou,J. A. Blackmans, we consider classic heuristics adapted to our setting: A greedy heuristic and a local search heuristic. We study their properties for plurality elections, approval elections, and ordinal elections, and evaluate their quality experimentally. The bottom line of our experiments is that the heuristic

Finally, under a variety of constraints, we establish that no polynomial time constant factor approximation algorithm can exist for computing the cardinality of a minimum set
