Planet Wator simulation |
Planet Wator simulation with fish and sharks.
This program simulates the planet WATOR as described in Scientific American Computer
Recreations column, Dec 1984. WATOR (or Wa-Tor) is a toroidal (donut-shaped) planet
inhabited by fish and sharks. The fish feed on a ubiquitous plankton and the sharks
feed on the fish. Time passes in discrete jumps or cycles. During each cycle, fish
move randomly to an unoccupied square, and reproduce if old enough. Sharks move to
a square occupied by a fish and eat it, if possible, or move to an open square if no
meals are available. Sharks will also breed if old enough, but will starve if they
do not eat within a specified period of time.
Parameters selected at the beginning of the run are as follows:
- nfish: Number of fish at start of run-distributed randomly.
- nsharks: Number of sharks at start, also distributed randomly.
- fbreed: Number of cycles a fish must exist before reproducing.
- sbreed: Number of cycles sharks must exist before reproducing.
- starve: Number of cycles a shark has to find food before starving.
On the screen, fish are green and sharks are blue. After the initial screen is
displayed, press any key to start the simulation. During the run, pressing any key
will stop the program.
