Struct LiftProjectConfig 

pub struct LiftProjectConfig {
    pub max_cuts: usize,
    pub variable_selection: VariableSelectionStrategy,
    pub cut_violation_tol: f64,
    pub ls_strengthening: bool,
    pub int_tol: f64,
    pub max_rows_per_var: usize,
}

Configuration for the lift-and-project cut generator.

Fields

max_cuts: usize

Maximum total number of cuts to generate in one call to generate_cuts. Default: 50.

variable_selection: VariableSelectionStrategy

Strategy for choosing which fractional variable to lift on.

cut_violation_tol: f64

Minimum cut violation threshold. A cut with violation ≤ this value is discarded as numerically insignificant. Default: 1e-6.

ls_strengthening: bool

Whether to apply Lovász-Schrijver SDP-based strengthening to generated cuts. Produces stronger cuts at higher computational cost. Default: false (pure LP-based lift-and-project only).

int_tol: f64

Tolerance for considering a variable value integral. Variables with |x_j - round(x_j)| ≤ int_tol are treated as integer. Default: 1e-8.

max_rows_per_var: usize

Maximum number of constraint rows to consider per fractional variable (before bound augmentation). Default: 1000 (effectively unlimited for most problems).
