There are two types of files: XXXM.csv and highways.csv.

XXXM.csv: This file contains information about each rule highway ID. Each row corresponds to a specific rule, numbered sequentially. For example, row 54787787 shows 497642, which is the highway ID for the rule 54787787.
highways.csv: This file provides detailed information about each highway ID. Each row stores a tuple (highway ID, period, dx, dy, winding) sorted by highway ID. Keep in mind that there might be gaps in the IDs.

Highway ID 0 means that no periodic pattern was found, and ID 1 means that the ant escaped some large bound but the period could not be computed due to it being too large or not really forming a periodic pattern.

First steps

Install Java: You need Java 16 or greater to run the program.
Register: An account is needed in order to contribute.
Generate a token: Go to the settings page and click the button "Generate token" to create a unique secret token for you to login on the client.

How to run

Specify the number of CPU threads you want to use with the -w option. If the -w option is absent, it will use one thread.

java -jar langtonX.X.X.jar -w THREAD_COUNT

If this is your first time running the program add the option -u and your username. Once you run it, it will ask you the secret token previosly generated.

java -jar langtonX.X.X.jar -w THREAD_COUNT -u USERNAME

Once you are logged in you will get an output like the following.

# java -jar langton1.0.2.jar -w 3
