where 𝑑 𝑗 𝛼𝛽 (𝜑 𝛼 , 𝜑 𝛽 ) is given by |𝜑 𝑗 𝛼 -𝜑 𝑗 𝛽 | and A -D are parameters for the repulsive (A, B) and attractive components (C, D). The dihedral-specific swarm energy evaluations entailed by Eq (1) are inherently suited to distribution with the domain decomposition algorithm as implemented in the molecular dynamics framework of the pmemd module of AMBER14. 37
