“…Although the conditions of existence of solutions for the planar formulation of the problem are natural, in the case of axial formulation the situation is more complex. The conditions for the existence of solutions of this formulation were described, for example, by Morávek and Vlach (1967) or Vlach (1986).…”

“…3 if the base number is 5. Due to the complexity of finding even a feasible solution to this optimization problem, (see, e.g., [50,51]), the statistical agencies apply a simple technique called Random Rounding (see, e.g., [52]). In this technique each cell value is rounded up or down in accordance with a probabilistic distribution.…”

“…If the problem is feasible, how many feasible solutions exist? The feasibility problem was previously studied on by Moravek and Vlach [50] and Vlach [51]. Irwing and Jerrum [37] and De Loera and Onn [89] also analyze the complexity of the counting problem.…”
