Most efficient solution: in it sa ha ge gu ca ir co se be ru mo sp au no le li et br bo uz (44 characters)

My combo has 2 fewer characters:

au

br

ch

co

do

ga

ge

gu

in

is

it

la

mo

no

sa

so

sp

su

to

tu

un

Used these pairs to make the nonsensical sentence "to undo col age is such brit mono so tug us a gasp in au". I can't touch type so 7 seconds will have to do ;)

Yes, you're right! I think 42 is optimal, my reasoning must have been flawed last time unless any of the relevant type-ins have changed.

Level 66

42 is indeed optimal.

This is a set-cover problem, so there's no clever solution (as far as anyone knows). But there are strategies to reduce the problem size:

For example, typing "VA" is never better than typing "IT", because they both cover Vatican City and Italy, but "IT" also covers other countries. Likewise, everything that covers Uruguay also covers Brazil, so you don't need to try to cover Brazil separately.

This allows me to reduce the problem to 55 letter-pairs and 96 countries.

I then try every combination: for every country, I choose a letter-pair that covers the country, and continue until every country is covered or until I've picked 21 letter-pairs; then I backtrack and choose a different letter-pair. This search runs in about 10 minutes on my computer.

It finds several 42-letter solutions, and nothing shorter. One possible 42-letter solution is:

CH CO MO GE GU SA SO TU LA IN AU NO UN BR IS BU DO GA SP ET IT

0.3% of people who took this got 100% xddd

I'm one of them.

It's just how fast you recognize which small countries you missed.

Lebanon, Gambia, and the microstates of europe were missed quite a bit lol

Edit: 51,000 people took this, and if 0.3 % of people got 100% does that mean that only 153 people got 100%? If so wow...
