Thank you Gabor, this solution is superbe (you never stop amazing me :)
Now... it only finds _one_ of the multiple minimum solutions. In the toy 
example, there are two minimum solutions, hence I reckon the output should 
have been a list with:
[[1]]
[1] 1 0 1

[[2]]
[1] 0 1 1

Also, thanks to Duncan and yes, I do very much care finding the smallest 
possible solutions (if I correctly understand your question).

It seems that lp function is very promising, but can I use it to find _all_ 
minimum solutions?
