%X Sufficient
conditions are given for any local minimum of a function of two integer
variables to be a global minimum. An example is given </span><span style=\"font-family:Verdana;\">to</span><span style=\"font-family:Verdana;\"> show that
a function of two integer variables need not be discrete convex for this
condition to hold.
