It was pointed out to me that you are actually trying to maximise the
function, sorry, didn't read the command carefully enough.
And I also noticed that my comments were anyhow wrong, for
minimisation the points (x,x) and not (x, 1-x) would be the solutions;
must have also misread the function as |x1+x2|...
Looks as if I need more coffee to wake up and get my brain going...
