Gridworld (tuxdb.com)

Hi Guys, I just updated Gridworld to version 1.23. Unfortunatelly, older saved worlds, creatures, and simulations settings no longer work. If you have any older simulations you would like to finish, please contact me. patchnotes: changes: - Linux support - Slight (UI) performance improvement - Improved physics for multicellular creatures that are connected in a chain. (connector) - Introduced new neuron "chain end". chain end neuron is used for movement of chained creatures (creatures connected in a chain) - Added a new font with upper and lower case chars - Font can be selected in the options menu in the main menu - Exporting creature now also exports a picture of the creature (for future workshop support) - The loading world menu in the main menu now shows a preview texture of the selected world - Increased maximum gravity value - Decreased absolute maximum of creatures from 8000 to 4000 - Reintroduced blank neuron - Added reset button for UI settings - Introduced tag variable for tiles - Tiles can now be replaced by tag - Opening a neuron window now closes previously opened neuron windows. bug fixes: - Fixed option for rendering native cursor - Fixed bug in which amount of piston neurons was not shown in the Microscope menu - Fixed bug in which loading simulation settings would break the UI of the world editor. - Exporting simulation results works again.

What is Gridworld?

Gridworld is an artificial life / evolution simulator in which abstract virtual creatures compete for food and struggle for survival. Conditions in this two-dimensional ecosystem are right for evolution to occur through natural selection.
Creatures live short and replicate fast. Evolution can therefore be observed in hours or days instead of thousands of years.

how does it work?

Creatures in Gridworld are a simple and abstract versions of biological life. They can be recognized as colored blocks moving around the grid. Just like in nature,
creatures have DNA, a digital code that describes the morphology of the creatures. in Gridworld, the dna describes the morphology of the neural network (brain) of the creature. In turn, the brain decides how the creature behaves during its life.
When a piece of dna is copied when creatures reproduce, there is a small chance of mutation in the dna. This leads to diversity in the dna pool. Natural selection causes those creatures with the best adapted genes to have more offspring. This causes the best adapted genes to increase in numbers while the weaker genes are decreasing in numbers and are eventually rooted out.
Through this process of natural selection, creatures become increasingly well adapted to their environment within each generation. And thus, evolution occurs.

How to use it?

The cool thing about evolution is that it is an autonomous process that requires no guiding hand.
You can simply start a simulation and take your hands of completely. When you come back to check after a day or two, you will find a thriving eco system of virtual creatures. You can do more than just simply observing though. Gridworld's simulations are highly customizable. The user interface allows you to tweak any simulation parameter or change the environment as you like.
This way you can set up your own experiments and watch as your creatures adapt to the world and conditions that you provide for them.

what is the goal?

Gridworld is not a game but an evolution simulator.
There is no real goal in Gridworld other than playing, learning, observing and experimenting.
The role of the user is mainly passively observing the process of evolution as it unfolds in the simulation.
