Fields

fk_csd: Vec<Vec<u64>>

FK cluster size histogram per temperature: hist[s] = count of size-s clusters.

overlap_csd: Vec<Vec<Vec<u64>>>

Per-mode overlap cluster size histogram: [n_modes][n_temps][n_spins+1]. Counts clusters of the sites a move acts on; the sites it leaves alone are not size-1 clusters. CMR acts on every site.

top_cluster_sizes: Vec<Vec<[f64; 4]>>

Per-mode average relative size of k-th largest overlap cluster: [n_modes][n_temps][4]. Zero for a mode that never ran during measurement, and where fewer than k clusters exist.

fk_updates: Vec<u64>

Recorded FK cluster updates per temperature, summed over replicas. Empty unless FK clusters update spins.

fk_visited_spins: Vec<u64>

Spins those updates visited: the flipped cluster for Wolff, every spin for Swendsen-Wang. For a ferromagnet the mean Wolff cluster size fk_visited_spins / fk_updates estimates N ⟨m²⟩, and for any model it converts autocorrelation times from cluster updates to sweeps.

overlap_moves: Vec<Vec<OverlapMoveCounts>>

Per-mode move counters of the recorded overlap updates, [n_modes][n_temps]. Empty for a mode that publishes none (replica Monte Carlo).

rmc_edges: Vec<RmcEdgeCounts>

Replica Monte Carlo counters of the recorded updates per temperature edge, [n_temps - 1]; empty without an rmc mode.
