It might, but if you're going to evaluate all possibilities, who cares? As in, if you are worried about a scenario such as the following, where the 10 gets bagged "solo" despite there being a -5 farther down the pipeline:      ( [ 9 ], [ 10, -5], [ 11 ] )
Then later on you will inevitably evaluate a scenario where the -5 is inserted earlier.      ( [ 9, -5, 10 ], [11] )
So, taking the "brute force" approach, you might lose points for style, but you get the job done, no?

Has anyone ever pointed out to a grocery checker that the bagging problem was NP-complete? The result might be similar to explaining that dogs can solve quadratic equations (i.e. capturing a frisbee in a parabolic arc while in linear motion).

    Has anyone ever had a grocery bagger that optimally bagged their groceries? Fortunately, the greedy heuristic which baggers generally use is not NP-complete =)

[Corion]: Sane Dots Supplies - your brand manufacturer for satisfying experiences!
[choroba]: preparing the trip to Vietnam + buying a new car = enough fun
[Corion]: choroba: Yeah, that's a lot of "fun" for one week...
[Corion]: I guess I should stage some product photos for Sane Dots Supplies ;)
[marto]: I had some ideas about that Corion
[marto]: I'll send a message over the weekend maybe :P
[Corion]: choroba: I avoided the "fun" of emergency shopping for a new flat iron by trying the flat iron without the timer that sat between it and the mains power. Seems as if just the timer is broken.
[Corion]: marto: Heh, would be cool!
Corion munches on the traditional German winter fruit, strawberries. Imported from Spain at the price of EUR 0.77 per 150g - not really cheap but surprisingly good for a winter produce
