Sandwich and probe problems for excluding paths
Figueiredo, Celina Miraglia Herrera de; Spirkl, Sophie (Elsevier, 2018-12-31)Let Pk denote an induced path on k vertices. For k ≥ 5, we show that the Pk-free sandwich problem, partitioned probe problem, and unpartitioned probe problem are NP-complete. For k ≤ 4, it is known that the Pk-free sandwich ... -
The Sandwich Problem for Decompositions and Almost Monotone Properties
Chudnovsky, Maria; Figueiredo, Celina Miraglia Herrera de; Spirkl, Sophie (Springer Nature, 2018)We consider the graph sandwich problem and introduce almost monotone properties, for which the sandwich problem can be reduced to the recognition problem. We show that the property of containing a graph in C as an induced ...
