{{{
sage: p = MixedIntegerLinearProgram()
sage: b = p.new_variable()
sage: p.add_constraint(int(1) <= b[0] + b[1] + b[2] <= int(2))
sage: p.show()
Maximization:
Constraints:
x_0 + x_1 + x_2 <= 2.0
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)
}}}
The code above works on the command-line. In a script, you can do without
the `int()`.
