Bikepacking List

Considerations

  • Volume is worse than weight
  • Eat before you’re hungry

Necessary

  • Food (things you can consume quickly and on the bike)
  • Water (more than 2 water bottles. A camelback in a framebag works well here)
  • Shelter with rain fly

Conway's Game of Life

Conway's Game of Life

Conway's Game of Life is a set of rules which define a cellular automata. Read more about it in Wikipedia. Your task is to write a Conway's Game of Life (GOL) simulation.

GOL consists of a two-dimensional grid of cells. Each cell is either alive or dead. Your simulation should calculate the grid over a user-specified number of generations. To calculate the next generation you apply the following rules to each cell in the grid and the resulting grid is the next generation.

Rules

  • Any live cell with fewer than two live neighbours dies, as if caused by under-population.
  • Any live cell with two or three live neighbours lives on to the next generation.
