### p.show() at MixedIntegerLinearProgram results

? would appreciate it if someone could explain me how the p.show() method works (p=MixedIntegerLinearProgram)... More precisely : lets say we have the following Linear Program:

p=MixedIntegerLinearProgram()
w=p.new_variable()
p.set_objective(w[0]- w[1]) #<---- Look here


the result from p.show() is

Maximization:
x_0 -x_3   #<----and here
Constraints:
4.0 <= -x_0 +x_1 +2.0 x_2 <= 4.0
3.0 <= x_0 +x_2 +x_3 <= 3.0
Variables:
x_0 is a continuous variable (min=0.0, max=+oo)
x_1 is a continuous variable (min=0.0, max=+oo)
x_2 is a continuous variable (min=0.0, max=+oo)
x_3 is a continuous variable (min=0.0, max=+oo)


why SAGE shows a different objective function?
