The maximum flow problem is an important graph problem with a wide range of applications. In this paper, we present a lock-free multi-threaded algorithm for this problem. The algorithm is based on the push-relabel algorithm proposed by Goldberg. By using re-designed push and relabel operations, we derive our algorithm that finds the maxi- mumflow with 0{\V\2 \E\) operations. We demonstrate that as long as a multi-processor architecture supports atomic 'read-update-write' operations, it will beâ€¦Â CONTINUE READING
