evolve-life-bitwise

Native evolve.life

Conway's Game of Life simulator using bitwise-packed rows. Stores 32 cells per integer for cache-friendly bulk neighbor counting. Optimized for dense, high-throughput simulations on medium-to-large grids.

Phenotype

Input

PropertyType Description
grid array Custom initial grid (2D array of 0s and 1s). Ignored if preset is set.
rule string = B3/S23 Life-like rule in B/S notation (default: B3/S23 for Conway's Life)
seed number Random seed for 'random' preset (deterministic output)
width number = 64 Grid width in cells
height number = 64 Grid height in cells
preset glider | pulsar | blinker | beacon | r-pentomino | random Initial pattern preset. Overrides grid if provided.
generations number = 100 Number of generations to simulate

Output

PropertyType Req Description
extinction boolean Whether all cells died before final generation
final_grid array Grid state after all generations
alive_count number Number of live cells in final grid
stabilized_at number Generation at which the grid stabilized (-1 if not stabilized)
ascii_snapshot string ASCII art of the final grid state (max 80x40)
cells_processed number Total cell evaluations (width * height * generations_computed)
peak_population number Maximum live cells observed across all generations
generations_computed number Actual number of generations computed (may be less if stabilized/extinct)
