	The reason that the Pointless Optimisation Game exists as a concept is that the bounding box metric was chosen to determine the "smallest" guns in [[Dieter and Peter's gun collection]] from the 1990's. That convention continued to be followed in later collections of glider guns maintained by [[Jason Summers]], [[Chris Cain]], and [[Adam P. Goucher]]. Bounding-box-optimized guns started getting an increasing amount of attention around the year 2000, when the focus began to shift toward creating a complete collection of optimized guns for all periods between 14 and 1000. That project was completed using [[Hersrch]] in September 2003.

	The slightly disparaging tone of the phrase "pointless optimisation game" is due to the fact that obsessively optimising a gun to reduce its rectangular bounding box to the lowest possible area does not necessarily produce the most generally useful gun. An [[edge shooter\|edge-shooting]] gun might well be much more useful in larger patterns. For example, a gun with a small bounding octagon or narrow diagonal diameter may allow many copies to be packed more efficiently into a larger [[shotgun]] pattern like the ones found in bounding-box-~~optimized~~ guns for constructible spaceships. Alternatively, a gun optimised for [[population]] could allow for easier reduction of patterns such as [[SKOP]]s and [[sawtooth\|sawteeth]].
