Struct ContractionOptions 

pub struct ContractionOptions {
    pub tolerance: f64,
    pub max_bond_dim: usize,
    pub method: CompressionMethod,
}

Options for MPO-MPO contraction with on-the-fly compression.

Examples

use tensor4all_simplett::ContractionOptions;

let opts = ContractionOptions::default();
assert!((opts.tolerance - 1e-12).abs() < 1e-15);
assert_eq!(opts.max_bond_dim, usize::MAX);

Fields

tolerance: f64

Relative truncation tolerance during contraction.

max_bond_dim: usize

Hard upper bound on bond dimension.

method: CompressionMethod

Decomposition method for intermediate compression.
