Infinite Compression Algorithm

Ok. I studied Wolfram's ideas. And he implies, that there is a simple cellular automata, that can produce any structure in existence. The only problem left is locating that structure in the automata's output.

Hey, FrozenVoid, can you do that?

There is a way to compress with Conway's Game of life.
1.Load the file as final state of Conway's game of Life X/Y grid.
2.Run the algorithm in reverse to find a state which minimizes the amount of live cells.
This is the step which is problematic:
Will the number of live cells decreases or increase? Maybe some ruleset guarantees growth in one direction, that would be suitable for this task(original 23/3 ruleset is too chaotic imho).
3.Compress it with zip/gzip.
Write the file+ number of backward generations.
4.Decompress the file.
5.Run Conways game of life normally for number of generations specified.
6.Record the original file.
