Abstract. We propose a proof-theoretic approach for gaining evidence that certain parameterized problems are not fixed- parameter tractable.

Mar 23, 2012 · In [6], parameterized proof complexity is given as a program to gain evidence that. W[2] is different from FPT, while in [7] the program is ...

This project will develop new techniques and reassess current techniques in proof complexity and computational complexity for their applicability in ...

We propose a proof-theoretic approach for gaining evidence that certain parameterized problems are not fixed-parameter tractable.

A dichotomy theorem is established that splits the exponential case of Riis's complexity gap theorem into two subcases, one that admits proofs of size ...

Recall that the definitions of parameterized complexity are tailored to address complexity issues in situations where we know that the parameter is relatively ...

Here we propose a notion of core for parameterized proof complexity: the core of a parameterized contradiction (F, k) is a subset of clauses F0 ⊆ F whose size ...
