Is it possible to use one of the built in routines for linear programming with algebraic numbers, instead of floating point numbers.

I have to solve a problem on algebraic operators exactly, not numerically.

I do not think so. But with the PPL solver you can solve LP over Q.

Look at that :

sage: p = MixedIntegerLinearProgram(solver="PPL")
sage: x = p.new_variable()                       
sage: p.add_constraint(2*x[1]+3*x[2] == 1)
sage: p.solve()
0
sage: p.get_values(x)
{1: 0, 2: 1/3}

Thank you. I already adapted an existing Python code!
