Describe the bug I try to formulate a problem as the attached figure, but when I convert the model to the Ising model, "model.to_ising()", the python kernel crashed. Similar conditions occurred when the number of spins are over 200. How many spins do Pyqubo support? bug

@zhuo-liu-scut Thank you for reporting the issue. I'll look into it.

@zhuo-liu-scut Could you share the complete code to reproduce the crash? (In the code above, G_radius is not defined.)

joeliuz6 commented 2 years ago

G_radius is a class object in Python NetworkX package. G_radius.edges() is formulated as below, which is related to the problem. ![Uploading G_radius.PNG…]()
