Progress information during solving.

Fields

iteration: u32

Current iteration/generation number.

total_iterations: u32

Total expected iterations (0 if unknown).

utilization: f64

Current best utilization (0.0 to 1.0).

best_fitness: f64

Current best fitness value.

items_placed: usize

Number of items placed.

total_items: usize

Total number of items.

elapsed_ms: u64

Elapsed time in milliseconds.

phase: String

Current phase/stage description.

running: bool

Whether the solver is still running.
