Optimal FPT-Approximability for Modular Linear Equations
Konrad K. Dabrowski, Peter Jonsson, Sebastian Ordyniak +2
We show optimal FPT-approximability results for solving almost satisfiable systems of modular linear equations, completing the picture of the parameterized complexity and FPT-appro…
Parameterized Approximability for Modular Linear Equations
Konrad K. Dabrowski, Peter Jonsson, Sebastian Ordyniak +2
We consider the Min--Lin problem: given a system of length- linear equations modulo , find of minimum cardinality such that is satisfiable…
Finding -Cuts in Probe -Free Graphs
Konrad K. Dabrowski, Tala Eagling-Vose, Matthew Johnson +2
For an integer , the -Cut problem is that of deciding whether a graph has an edge cut in which each vertex is adjacent to at most vertices on the opposite side of t…
Towards a Parameterized Approximation Dichotomy of MinCSP for Linear Equations over Finite Commutative Rings
Konrad K. Dabrowski, Peter Jonsson, Sebastian Ordyniak +2
We consider the MIN-r-LIN(R) problem: given a system S of length-r linear equations over a ring R, find a subset of equations Z of minimum cardinality such that S-Z is satisfiable.…
