{{w|Andrey Kolmogorov}} was a mathematician who worked, among other things, on defining computational complexity. Roughly speaking, the {{w|Kolmogorov complexity}} of a string (of bits, words, symbols, etc.) is the shortest description that allows an accurate reconstruction or, in some variants, the length of the smallest program which will output the original string.

{{w|Andrey Kolmogorov}} was a mathematician who worked, among other things, on defining computational complexity. Roughly speaking, the {{w|Kolmogorov complexity}} of a string (of bits, words, symbols, etc) is the shortest description that allows an accurate reconstruction (or, in some variants, the length of the smallest program which will output the original string). Cueball's method of giving directions is very reminiscent of Kolmogorov's method of determining complexity.
  
[[Cueball]]'s method of giving directions is very reminiscent of Kolmogorov's method of determining complexity. However, it is unlikely they know all the presidents, nor can calculate prime numbers in their heads, and so will have trouble with certain parts. These directions may have minimal Kolmogorov complexity, but they are non-intuitive and are likely not the shortest or quickest way to get there, considering that they consist mostly of left turns.

This is not the first time Cueball has had [[783|difficulties with directions]].
 
 
This is [[783: I Don't Want Directions|not the first time]] Cueball has had difficulties with directions, and here we see he hates giving directions as much as he hates receiving them.
 
 
 
The joke in the title text is that Cueball just sent his friend to a store to buy a GPS device to give him the correct directions. (By the time this comic was published, GPS-enabled smartphones had already largely displaced dedicated GPS devices,<ref>https://www.nytimes.com/2010/11/15/technology/15iht-navigate.html</ref> but Cueball could be talking to a person who does not wish to own a smartphone.)
 
  
 
The superfluousness of giving directions as opposed to using a GPS is the subject of [[783: I Don't Want Directions]].

:Cueball: Ok, starting from your driveway, take every left turn that doesn't put you on a prime-numbered highway or street named for a president.

:When people ask for step-by-step directions, I worry that there will be too many steps to remember, so I try to put them in minimal form.
