Problem 1976. Kaggle: Reverse Game of Life - Create Isle prior State
Kaggle's Conway's Reverse Game of Life contest inspires this Isle Single Evolution step in Life challenge. The kaggle contest runs from Oct-14-2013 thru Mar-02-2014. References: Game of Life at Wolfram. Wiki Life.
1. Any live cell with fewer than two live neighbors dies, as if caused by under-population. 2. Any live cell with two or three live neighbors lives on to the next generation. 3. Any live cell with more than three live neighbors dies, as if by overcrowding. 4. Any dead cell with exactly three live neighbors becomes a live cell, as if by reproduction. 5. No wrap around. Beyond edge is zero. Eight Neighbors.
Create an Isle that will evolve in one step to the given Isle state. An Isle is a morphing matrix that may contain non-periodic and interacting animals. The Isle is pre-evolved and will have >10 live cells. Multiple solutions are possible. Imperfect solutions are allowed. This is a Performance Challenge.
Input: Isle, 10x10 binary, 100 Isles
Output: Isle_Predict, a matrix that will evolve to Isle
Scoring: 1000 * ( Errors / Total_points )
Example: (Errors=0 and 100 Total Points)

Finally, a problem where random smart guesses leads to a good solution. Trying all possibilities is not feasible, and there are many states that can have the same output.
The Kaggle challenge was to find those previous states with machine learning, but the Conway game of life is not reversible. I recommend playing with it a little https://playgameoflife.com/
