    On the complexity of reconstructing H-free graphs from their star systems

  • Original language description

    We prove that when H is a path or a cycle on at most 4 vertices the problem is polynomial time solvable. In complement to this result, we show that if H belongs to a certain large class of graphs the H-free Star System problem is NP-complete. In particular, the problem is NP-complete when H is either a cycle or a path on at least 5 vertices.

    Výpočetní složitost rekonstrukce H-prostých grafů z jejich systémů okolí

  • Czech description

    Ukažujeme, že problém rekonstrukce H-prostých grafů ze systémů okolí jejich vrcholů je polynomiálně řešitelný, pokud H je cesta nebo kružnice na nejvýše 4 vrcholech, a NP-úplný, pokud je to cesta nebo kružnice s alespoň 5 vrcholy.
