Faster Exact Algorithms for Some Terminal Set Problems,ich intersects all “structures” (such as cycles or paths) passing through the vertices in .. We call this class of problems as .. In this paper we introduce a general method to obtain faster exact exponential time algorithms for many terminal set problems. More precisely, we show that.A key feature

Parameterized Algorithms for Modular-Width,herefore desirable to find a different structural graph parameter which is as general as possible, covers dense graphs but does not incur such a heavy algorithmic penalty..The main contribution of this paper is to consider a parameter called modular-width, defined using the well-known notion of modu

A Faster FPT Algorithm for Bipartite Contraction,fixed-parameter tractability of the problem was shown by Heggernes et al. [13], with an algorithm whose running time has double-exponential dependence on .. We present a new randomized FPT algorithm for the problem, which is both conceptually simpler and achieves an improved . running time, i.e., av

However, some issues are not addressed by this framework, including the existence of Turing kernels such as the “kernelization” of .(.) into a disjunction over?. instances each of size poly(.).
