Retina, score 1 The empty program counts the number of matches of the empty regex in the input (which is the empty string). That's exactly 1 match, so it prints 1. Try it online.

Pyth, 10 T First attempt at using Pyth. Having had the question clarified, it seems 10 will be the smallest number. In Pyth the letter T starts off as the number 10, so this simply prints 10 which is larger than the length of the source code. You can try it here.

Ruby, 29 bytes ->s{!s[/[^aeiou]{3}|[jqxz]/]} Hopefully I've got this right - it's my first time programming in Ruby. I actually did all my testing in Python, but import re was far too long for me. This is an anonymous function which takes in a string and outputs true/false accordingly. It uses a regex which looks for one of the following two things: ...

bc, 10 A Luckily, bc prints the result of the last expression by default. A is interpreted as a hex digit, so results in 10.

C++, 97 95 93 91 86 83 82 81 79 characters My strategy is fairly simple - an evolution algorithm that can grow, shrink, swap elements of and mutate valid sequences.

(EDIT: This first part refers to the original phrasing of the question.) First, (!x&&!y&&!z) returns a boolean, which makes ?true:false entirely redundant. It's basically like using if (x == true) return true; else if (x == false) return false; instead of return x;. That gives you !x&&!y&&!z (EDIT: The remainder ...

Python 2, 44 bytes a,b,c,d=sorted(input()) print min(c-a,d-b)*2 Try it online! Sorts the input as a,b,c,d, in ascending order, takes the smaller of c-a and d-b, and doubles it. Why does this work? First, note that when we change an element to maximize to total cyclic sum of distances, it's optimal (or tied for optimal) to change it to equal a neighbor, ...

Mathematica (version 9), 165 bytes The nice, short ConvexHullMesh function that Greg Martin used was only introduced in Mathematica version 10, so I thought I'd make an attempt without it, using my ancient Mathematica version 9. I managed to get it slightly shorter, though! It's a function that takes and returns a list of strings (with ., # and o as the ...
