Fast Local Search Algorithm for Weighted Feedback Arc Set in Tournaments
We present a fast local search algorithm that finds an improved solution (if there is any) in the k-exchange neighborhood of the given solution to an instance of WEIGHTED FEEDBACK...

Reasoning about online algorithms with weighted automata
We describe an automata-theoretic approach for the competitive analysis of online algorithms. Our approach is based on weighted automata, which assign to each input word a cost in...
