Toshiba Simulated Bifurcation Machine (SBM)

What is
the Simulated Bifurcation Machine?

Originated from research on quantum bifurcation machines,
the SBM is a practical and ready-to-use ISING machine that solves large-scale "combinatorial optimization problems" at high speed.

※Simulated Bifurcation Machine=SBM

Software

No need for special hardware; can be implemented on general-purpose computers.

Large-scale

Solved the 1 million spin MAX-CUT problem in a PC cluster environment.
Horizontal scaling can be achieved by using tens of computers as a resource.

Fast

100 times faster than a simulated annealing method^*2, now widely used to solve a Ising problem.

*1：Spin：unit of Ising problem size.
*2：Based on our environment.

Comparison with
the existing Ising machines

Achieved the scale required to solve real-world problems.
