Approximation algorithm for Maximum 3-Cycle cover problem

In the maximum 3-cycle cover problem, given an edge weighted complete directed graph we ask for a collection of node-disjoint cycles each of length at least three whose weight is maximum among all such collections. I present a 3/4-approximation algorithm for the problem. This result is obtained via a new decomposition technique for the fractional solution of an LP formulation of the problem.
