Query: On the behaviour of solutions to discrete time Lotka-Volterra equation   The time evolution of a class of completely integrable discrete
Lotka-Volterra s ystem is shown not unique but have two different ways chosen
randomly at every s tep of generation. This uncertainty is consistent with the
existence of constant s of motion and disappears in both continuous time and
ultra discrete limits.
