| You are provided a modded version of Minecraft which allows you to connect to a running game world to obtain a robot called a "turtle". When you close the connection, the robot disappears. You may also open multiple connections to obtain multiple robots which can then work in parallel. | You are provided a modded version of Minecraft which allows you to connect to a running game world to obtain a robot called a "turtle".

| Even though most tasks can be solved using only one turtle, parallelization is the key to do them quickly. This introduces a few synchronization issues that you need to deal with: how to divide the task among the turtles and how to prevent turtles from crashing into each other. | Even though most tasks can be solved using only one turtle, parallelization is the key to do them quickly.

| - | ==== Installing from scratch ==== | ||
| - | If you want to run the mod at home, you need to install [[http://files.minecraftforge.net/maven/net/minecraftforge/forge/index_1.8.9.html|Minecraft Forge for Minecraft 1.8.9]] over an existing Minecraft Installation to add the "forge" profile to the launcher. Then copy [[http://ttsil.net/misc/turtlecraft/cc.jar|the mod]] into the ~/.minecraft/mods folder. After launching the first time with the mod installed, a configuration file with default values for the measured goal will appear in ~/.minecraft/config. | ||
