SmoothLifeL

A demonstration of SmoothLifeL, a continuous generalization of Conway's Game of Life that uses floating-point values to simulate fluid-like gliders and structures.

SmoothLife is a family of rules created by Stephan Rafler. It was designed as a continuous version of Conway's Game of Life - using floating point values instead of integers. This rule is SmoothLifeL which supports many interesting phenomena such as gliders that can travel in any direction, rotating pairs of gliders, wickstretchers and the appearance of elastic tension in the 'cords' that join the blobs. Run it for yourself: sourceforge.net/projects/smoothlife/ Add this line to the top of SmoothLifeConfig.txt and run the exe: 2 1 10.0 3.0 10.0 0.100 0.257 0.336 0.365 0.549 2 4 4 0.028 0.147 // L Or download Ready( code.google.com/p/reaction-diffusion) and open the included pattern: Patterns/smoothlife_smoothlifeL.vti Slides showing how the rule works: youtube.com/watch?v=iyTIXRhjXII Paper describing SmoothLife and SmoothLifeL: arxiv.org/abs/1111.1567 More videos by Stephan: youtube.com/playlist?list=PL69EDA11384365494&feature=plcp Original Google+ post: plus.google.com/110214848059767137292/posts/WtPBhYJswAe Details: Outer radius: 20.0 Radius ratio: 3.0 Birth range: 0.257 - 0.336 Survival range: 0.365 - 0.549 Alpha_n (outer sigmoid width): 0.028 Alpha_m (inner sigmoid width): 0.147 Timestep: 0.05 (Euler integration) Frames: 10819 (saving 1 image per 8 timesteps) Total time units elapsed: 4327.6 World size: 512x512, with toroidal wrap-around. Color representation: linear mapping of [0,1] onto [black,white] Computation time: 74 minutes on an nVidia GeForce GTX 460. That's in Ready and for a high quality version. For viewing it runs in realtime. Stephan's software (at the sourceforge link above) runs much faster because it uses FFT.
