Motivated by problems in optimization we study the sparsity of the solutions to systems of linear Diophantine equations and linear integer programs, i.e., the number of non-zero entries of a solution, which is often referred to as the [Formula Presented]-norm. Our main results are improved bounds on the [Formula Presented]-norm of sparse solutions to systems [Formula Presented], where [Formula Presented], [Formula Presented] and [Formula Presented] is either a general integer vector (lattice case) or a non-negative integer vector (semigroup case). In the lattice case and certain scenarios of the semigroup case, we give polynomial time algorithms for computing solutions with [Formula Presented]-norm satisfying the obtained bounds.
