Struct IterativeState 

pub struct IterativeState {
    pub iteration: u64,
    pub last_delta: f64,
    pub convergence_threshold: f64,
    pub max_iterations: u64,
    pub converged: bool,
}

State for tracking iterative algorithm convergence.

Used for algorithms like PageRank, K-Means, GARCH that iterate until convergence.

Fields

iteration: u64

Current iteration number.

last_delta: f64

Last computed delta/error value.

convergence_threshold: f64

Convergence threshold.

max_iterations: u64

Maximum allowed iterations.

converged: bool

Whether algorithm has converged.
