"textContent": "**Authors:** Dmitry Gribanov, Tagir Khayaleev, Mikhail Cherniavskii, Maxim Klimenko, Dmitry Malyshev, Stanislav Moiseev\n\nWe study the standard-form ILP problem $\\max\\\\{ c^\\top x \\colon A x = b,\\; x \\in Z_{\\geq 0}^n \\\\}$, where $A\\in Z^{k\\times n}$ has full row rank. We obtain refined FPT algorithms parameterized by $k$ and $Δ$, the maximum absolute value of a $k\\times k$ minor of $A$. Our approach combines discrepancy-based dynamic programming with matrix discrepancy bounds in Komlós' setting. Let $κ_k$ denote the maximum discrepancy over all matrices with $k$ columns whose columns have Euclidean norm at most $1$. Up to polynomial factors in the input size, the optimization problem can be solved in time $O(κ_k)^{2k}Δ^2$, and the corresponding feasibility problem in time $O(κ_k)^kΔ$. Using the best currently known bound $κ_k=\\widetilde O(\\log^{1/4}k)$, this yields running times $O(\\log k)^{\\frac{k}{2}(1+o(1))}Δ^2$ and $O(\\log k)^{\\frac{k}{4}(1+o(1))}Δ$, respectively. Under the Komlós conjecture, the dependence on $k$ in both running times reduces to $2^{O(k)}$.",
