Graphs and Combinatorics, 2020 For any graph $G$, let $ι_{\rm c}(G)$ denote the size of a smallest set $D$ of vertices of $G$ such that the graph obtained from $G$ by deleting the closed neighbourhood of $D$ contains no cycle. We prove that if $G$ is a connected $n$-vertex graph that is not a triangle, then $ι_{\rm c}(G) \leq n/4$. We also show that the bound is sharp. Consequently,
