Struct UffOptimizer 

pub struct UffOptimizer {
    pub max_iterations: usize,
    pub force_threshold: f64,
    pub verbose: bool,
    pub num_threads: usize,
    pub cutoff: f64,
    pub history_size: usize,
    pub max_displacement: f64,
}

Optimizer for molecular structures using the FIRE (Fast Iterative Relaxation Engine) algorithm.

Fields

max_iterations: usize

Maximum number of iterations to perform.

force_threshold: f64

Threshold for the maximum force on any atom (kcal/mol/Å).

verbose: bool

Whether to print optimization progress to stdout.

num_threads: usize

Number of threads to use. 0 means automatic based on system size.

cutoff: f64

Cutoff distance for non-bonded interactions (Å).

history_size: usize

Number of steps to average for convergence criteria.

max_displacement: f64

Maximum distance an atom can move in a single step (Å).
