I'd like to be able to do linear programming to arbitrary precision. The documentation that I've found claims that both the glpk and PPL solvers should do this, but I haven't been able to get either to work.
As an example, the following code prints c to high precision, but the solutions only to 12 digits. Where should I look for guidance? Note: this seeks to maximize x+y given that 3x<=1 and 3y<=1, so the solution is (1/3, 1/3) Mike M R=RealField(100) c=Matrix(R, 2, 1, [-1, -1]) G=Matrix(R, 2, 2, [3, 0, 0, 3]) h=Matrix(R, 2, 1, [1, 1]) print c # To check the precision being used by "print" print sol=linear_program(c,G,h) print sol['x'] sol=linear_program(c,G,h, solver='glpk') print sol['x'] sol=linear_program(c,G,h, solver='PPL') print sol['x'] -- You received this message because you are subscribed to the Google Groups "sage-support" group.
