    Parameterized Approximations via d-Skew-Symmetric Multicut

    In this paper we design polynomial time approximation algorithms for several parameterized problems such as Odd Cycle Transversal, Almost 2-SAT, Above Guarantee Vertex Cover and Deletion q-Horn Backdoor Set Detec...

    Faster Exact Algorithms for Some Terminal Set Problems

    Many problems on graphs can be expressed in the following language: given a graph G = (V,E) and a terminal set T ⊆ V, find a minimum size set S ⊆ V which intersects all “structures” (such as cycles or paths) pass...
