On the complexity of edge subdivision to $H$-free graphs

Marta Piecyk, R. B. Sandeep · 2026

Subdividing an edge $uv$ in a graph replaces it by a path $u w v$ with one new vertex. For a graph $H$, the \textsc{$H$-free Subdivision} problem asks whether, given a graph $G$ and an integer $k$, on…

Minimum Temporal Spanners in Happy Graphs

Arnaud Casteigts, Hendrik Molter, Meirav Zehavi · 2026

Temporal graphs have edge sets that change over discrete time steps. Such graphs are temporally connected (TC) if all pairs of vertices can reach each other using paths that traverse the edges in a ti…

A Note on Interdiction of Linear Minimization Problems

Yu Cong, Kangyi Tian · 2026

Motivated by the FPTAS for connectivity interdiction of Huang et al. (IPCO'24), we isolate the part of the argument that does not use cuts. The setting is a minimization problem over a feasible-set fa…
