Operations Research is a field of mathematics in which optimal or near-optimal solutions are sought for complicated problems.
In the modeling of materials, we often optimize Ising models, in which the discrete variables on $\{-1,1\}$ or $\{0,1\}$ represent
spin-up particles ($\,\uparrow\,$) and spin-down particles ($\,\downarrow\,$), and we seek the optimal configuration of spins that minimizes the energy (i.e. the ground state of the system). The lowest-energy configuration can vary greatly, depending on the couplings between the spins, and this can give rise to different types of magnetism in the materials, such as ferromagnetism: 
, anti-ferromagnetism:
, or one of many other types of phases.
The 2001 book Optimization Algorithms in Physics by Alex Hartmann and Heiko Rieger claims in the introduction to be a "unique" book in cross-pollinating algorithms that are popular in operations research, with algorithms and applications in physics. For example, they mention simulated annealing, which was born in the physics community, but is now used by mathematicians to optimize non-physics problems such as optimizations in graph-cut problems or in finance, and parallel tempering which was introduced in a physics journal in 1986 and implemented in GROMACS, LAMMPS, CHARMM, and AMBER (materials modeling software), but was used for "maximum likelihood" problems by statistician C.J. Geyer in 1991. However, they also mention the "blossom algorithm" of computer scientist Jack Edmonds, which helps to solve Ising problems very efficiently when restricted to certain scenarios with planar spin configurations.
While this book might indeed have been the first book to bring so much from the operations research community into the materials modeling context, and vice versa, most of the references are from much earlier. This got me curious to find out, when did the separately growing operations research community start adopting Ising-optimization methods from the physics community and vice versa?
I found a book from one decade earlier, called "Spin glasses and related problems" (1991).
But then I found proceedings of a colloquium on Spin Glasses, Optimization and Neural Networks (1986).However the mathematical optimization literature about developments such as Jack Edmond's blossom algorithm (1961), makes no mention of Ising models (which physicists were trying to optimize since the 1920s) or simulated annealing type algorithms which Metropolis et al. published in Journal of Chemical Physics in 1953.
Between circa 1961 and 1986, these two communities somehow learned about each other, and I am curious to know which paper or conference might get credit for it?
