# Exploring the Universe

### From TradeWars Documentation Wiki

A Trade Wars universe consists of sectors connected by warps. Universes may have from 100 to 30,000 sectors, and each sector may have from one to six warps. Some warps are one-way. A default universe is 1,000 sectors, but the smallest commonly played is 5,000 sectors.

In mathematical terms, the universe is a directed graph. The sectors are its vertices and the warps are its edges. The shortest path from one sector to another can be computed using a breadth first search. Graph partitioning algorithms can be used to find tunnels and bubbles that can be divided from the rest of the universe by defending a few key sectors. The mathematical complexity of the universe is one of the things that many players find compelling about the game.
