## Abstract

Let G be a connected graph. Vertex cover is defined by A V G ( ) such that every edge in graph G is incident to at least one vertex in A . Edges cover is defined by B E G ( ) such that every vertex in graph G is incident to at least one edge in B . Complete flower graph is defined as tensor product from two cycle graphs C C m n for m 2 and n 2 which is denoted by mxn f . This paper discusses the minimum vertex cover and the minimum edge cover on complete flower graph based on their relationship with independence number, 1-factor and critical factor. Minimum vertex cover is equal to minimum edge cover if and only if the independence number is equal to maximum matching of complete flower graph. Minimum vertex cover is equal to independence number and is equal to half of vertex number if and only if complete flower graph have 1-factor. Minimum vertex cover is equal to half of vertex number if and only if complete flower graph is critical factor
