As a straightforward consequence, LEW-TLCM (and hence TLCM) has a fixed parameter algorithm that runs in 2O(k log k) + nO(1) time which improves on the previously best known algorithm with running time 2O(k3)n., We consider a simple generalization of two-layer crossing minimization problem (TLCM) called leaf-edge-weighted TLCM (LEW-TLCM), where we allow positive weights on edges incident to leaves, and show that this problem admits a kernel with O(k) edges provided that the given graph is connected.
