We study the existence of polynomial kernels for the problem of deciding feasibility of integer linear programs (ILPs), and for finding good solutions for covering and packing ILPs. Our main results are as follows: First, we show that theILP Feasibilityproblem admits no polynomial kernelization when parameterized by both the number of variables and the number of constraints, unless NP ⊆ coNP/poly. This extends to the restricted cases of bounded variable degree and bounded number of variables per constraint, and to covering and packing ILPs. Second, we give a polynomial kernelization for theCover ILPproblem, asking for a solution toAx≥bwithcTx≤k, parameterized byk, whenAis row-sparse; this generalizes a known polynomial kernelization for the special case with 0/1-variables and coefficients (d-Hitting Set).
