The world generation process uses a PRNG (Pseudo Random Number Generator) algorithm. A PRNG will produce a sequence of numbers that "looks" random even though the actual sequence of numbers will always be the same if the PRNG is started with the same seed value. Basically this means that if you run word generation with a certain seed value on your computer, and someone else runs world generation with the same seed value on their computer, the same sequence of random numbers will be generated on both computers. The practical impact of this is that someone else can generate exactly the same world that you generated by entering the same seed value that you used. | The world generation process uses a PRNG (Pseudo Random Number Generator) algorithm.

Open caverns and dense passageways are not mutually exclusive. When both are raised, bizarre results can occur, such as layers showing a combination of open caverns, a cluster of network passages, and natural walls sprinkling the inside of an otherwise open cavern.
