Approximation Algorithms for Complex-Valued Ising Models on Bounded Degree Graphs
We study the problem of approximating the Ising model partition function with complex parameters on bounded degree graphs. We establish a deterministic polynomial-time approximation scheme for the partition function when the interactions and external fields are absolutely bounded close to zero. Furt...
