swaps_to_permutation¶

torch_sim.monte_carlo.swaps_to_permutation(swaps, n_atoms)[source]¶

Convert atom swap pairs to a full permutation tensor.

Creates a permutation tensor that represents the result of applying the specified swaps to the system.

Parameters:

swaps (Tensor) – Tensor of shape [n_swaps, 2] containing pairs of indices to swap
n_atoms (int) – Total number of atoms in the system

Returns:

Permutation tensor of shape [n_atoms] where permutation[i]: contains the index of the atom that should be moved to position i

Return type:
