Several good (better!) examples on the internet, but an interesting exercise which gives a feel for:
- competition and extinction (sometimes in waves)
- adaptation within limits (in this case, within limits of program)
- different body shapes and motion evolve with different energy costs set
1. Bugs without energy cost based body size & motion: https://youtu.be/oEHHVbcns40?si=d1jwwlxVsn9HlE8A
2. Bugs with energy cost based body size & motion: https://youtu.be/GozinRa0NWo?si=OwJydbVpiRlO3TEs
3. Crazy crabs: https://youtu.be/AoF33UZ8_Yc?si=6N73koJQPkXM9LGl
This version is simple bugs and static food source only. In future I may try interacting bugs etc. Written in C++ with Microsoft Visual Studio Community 2022.
Enjoy.
