Convex-mixture graph Langevin optimizer

Put a gradient-Gibbs prior on differences between connected neural parameters rather than on individual parameters, and evolve the parameters with Langevin steps generated from randomly selected strictly convex component energies. The aggregate regularizer may be non-convex, but every sampled component has controlled curvature and outward drift, providing a practical stability mechanism for noisy training.

Soft-potential collision optimizer

Maintain a small population of neural-network parameter replicas and interleave ordinary gradient steps with Boltzmann/Kac-style binary collisions. Each collision preserves the pair's mean parameter vector and relative-distance norm while randomly rotating the relative direction, with collision frequency proportional to a regularized negative power of replica distance.
