Thanks for your info Eric,
Basically I want to do Hamilton optimization (Hamiltonian (control theory) - Wikipedia <https://en.wikipedia.org/wiki/Hamiltonian_(control_theory)>) using SageMath. This is what i tried, and where I have abserved this behaviour. So how should i define H in 'In [2]', so that 'In [4]' shows the expected result.
