Editing Transport puzzle (section)

==Description==
A transport problem is one in which objects are moved from a starting position to a destination position following the logical rules of the puzzle.<ref>Uduslivii, "Transport puzzles"</ref>  Transport puzzles do not necessarily involve any physical movement of objects, although they often do.  Rather, they are those puzzles that consist of finding a path through the [[state space]] of the puzzle to reach the goal state.<ref>Jarušek & Pelánek, p. 429</ref>  State changes can include rotations and distortions of the object being transported as well as its translation in space.<ref>Postma, p. 4</ref>

As in [[rearrangement puzzle]]s, no piece is ever lost or added to the board. In contrast to rearrangement puzzles, however, transport puzzles have all persons and objects follow certain routes given on the board; they cannot be lifted off the board and placed on faraway positions that have no visible connection to the from-position. Hence transport puzzles often mean that the player has to move (physical) objects in a very restricted space. The player may or may not be part of the game (either directly, or as a [[player character]] on the board).
