摘要：

The bounds on the size of the minimum feedback vertex set in meshes and butterflies were presented in the context of interconnection networks. Alternative ways were examined for computing small feedback vertex sets in two-dimensional meshes including a method which extends to meshes of higher dimensions. The bounds obtained for meshes were proved to be asymptotically optimal by giving almost matching lower bounds.
