,Constant Factor Approximation for Tracking Paths and Fault Tolerant Feedback Vertex Set,ation of the closely related . . problem. There, for a fixed integer . and a given vertex-weighted graph ., the task is to find a minimum weight set of vertices intersecting every cycle of . in at least . vertices. We give a factor . approximation algorithm for . . if . is a constant.

,On ,-Matchings and ,-Edge Dominating Sets: A 2-Approximation Algorithm for the 4-Edge Dominating Se in the most general cases 8/3 is the best approximation ratio known attainable in polynomial time [.]. Our algorithms are designed based on the most natural LP relaxation of .-EDS and maximal .-matchings (or its generalization).

L. Heilmeyer,A. Schittenhelm,B. Rudderm of the vector of loads of the machines. We present an EPTAS for this problem. Prior to our work only a PTAS was known in this non-renewable resource settings and this PTAS was only for the special case of our problem of makespan minimization on identical machines.

F. Kraus,O. Minkowski,A. Schittenhelm significantly improves over the previously best known competitive ratio of . and surpasses the current best .-competitive algorithm for the integral case. Moreover, our algorithm is deterministic in contrast to the randomized algorithms achieving the results mentioned above.
