Which the following is a very unique characteristic in the Assignment Model? O all X's are non-negative. all X variables have positive coefficients in left-hand-side (LHS) formula for each constraint. O all right-hand-side (RHS) value for each constraint is set as "1". O cost or time are the likely coefficients for the X variables in the objective function.
