Approximability and parameterized complexity of multicover by c-intervals

• c -Interval Multicover is Set Multicover with each input set being the disjoint union of c intervals (a c-interval). • We show 2-Interval Multicover to be W[1]-hard with respect to the parameter “number of 2-intervals used in the cover”. • We show 2-Interval Multicover to be APX-hard even if only...
