Approximating Maximum Subgraphs without Short Cycless a (. − 1)-approximation algorithm, which extends the result of Krivelevich from . = 3 to any .. Based on this, for odd . we give an algorithm for .. with ratio .; this improves over the trivial ratio of 1/2..Our main result however is for the .. problem with even values of .. For any . = 2., we gi

Approximating Single Machine Scheduling with Scenarioshted case. We show that our analysis is tight by providing a matching lower bound on the integrality gap of the LP. Moreover, we prove that the unweighted version is NP-hard to approximate within a factor less than 6/5. We conclude by presenting a polynomial time algorithm based on dynamic programmi
