v2.0.0

Simulated Bifurcation v2.0.0

⚠️ From this version onwards, the package is maintained only for versions of Python >= 3.9

What's Changed

🚀 Features

• Quadratic models can be created from SymPy Polys for a more mathematical and intuitive experience

from sympy import poly, symbols
import simulated_bifurcation as sb

x, y = symbols("x y")
sb.minimize(poly(3 * x**2 - 5 * x * y + 3 * y + 2), domain="spin")

• Optimization variables can now be defined on different domains

from sympy import poly, symbols
import simulated_bifurcation as sb

x, y = symbols("x y")
sb.minimize(poly(3 * x**2 - 5 * x * y + 3 * y + 2), domain=["spin", "int2"]) # x is in {-1, 1}, y is in {0, 1, 2, 3}

Quadratic models can still be defined from tensors or arrays, in any order

• Computations can be stopped using a keyboad interruption
• Clearer parameters names

Previous name	Previous values	New name	New values
ballistic	True or False	mode	"ballistic" or "discrete"
use_window	True or False	early_stopping	True or False

• Models' dtype and computation dtype are now the same and can only be torch.float32 or torch.float64
• sb.optimize has been removed, users shall now rely on sb.maximize and sb.minimize only
• GPU tests now cover the package

🐞 Bug fixes

• Initial energy tensor device the same as device defined in class
• CUDA computations are now only allowed with float32 or float64 values

New Contributors

• @Ali-Xoerex made their first contribution in #74
