>The only rule is “The structure needs to stand on its own.” Melt it down and recast it, duh. :)
For example, put the four Lego pieces on top of the Eiffel Tower, and you've now created a structure that is height "Eiffel Tower + Lego" - and it's made with those four pieces ('with', not 'only with' :) )

Bugger GA (whatever) thingies. I've got some super glue - stick all Lego bits together on their longest axis: problem solved as posed but probably not as intended. The large thing between my ears beats the crap out of a GA thingie any day, provided that the problem is loosely defined 8)
Does superglue work on Lego? I found that gluing pieces of plastic together (especially nice plastic like Lego) is the most challenging of all. Wood, paper, rubber, even metal with welding. The best experience I have with plastics is with PVC and the nasty chemical cements that temporarily dissolve the material. That said it would probably work well enough for this problem.
Ok, an even better one: http://imgur.com/a/FXhbH
To entertain myself, I gave this some thought before I clicked. I assumed exactly what the title says: which 4 lego pieces create the tallest structure that stands on it's own. Well, we need the biggest bricks we can find, my mind went to the ship hulls: https://www.ebay.com/p/?iid=282223262072&&&dispItem=1&chn=ps So how can we connect 2 of these together, and make it stand vertical? Or can we? It might be that we ne…
Envy, I think that's the word for the weird vitriol in this thread.
One commentator here questioned why is this on HN (and was DVd somewhat) There is the fact that dad teaches stuff to daughter. The lesson is fun and interactive. The concepts dealt with are pretty profound and can be quite deep: constraints, maxima and minima. Well done dad - you've covered some complex stuff in a fun and accessible way. Good skills. If anyone else doubts why this is valid Hacker News, they may want…
Slamming my nerd card down so hard the whole table spins around It's hacker news, not motivational team building shared insight news. I'd expect a GA solver which selected the four pieces which could be constructed into the tallest possible structure (with all the dirty tricks e.g. a boat hull attached to a wobbly assemblage of Giant Base/wing plates with a 12x24 brick balanced on the top), with a Speculation section…

Nah, they break one piece out, flip it and then put it back in, then mess up the pattern and gift it to someone for their birthday.
I got my girlfriend a 5x5x5 for her birthday and she accused me of swapping tiles when she got stuck on the last two. Almost ended the relationship.

Well, taking away the implicit rules, the limit becomes simply "the tallest structure we can build with current technology". For example, put the four Lego pieces on top of the Eiffel Tower, and you've now created a structure that is height "Eiffel Tower + Lego" - and it's made with those four pieces (' with ', not ' only with ' :) )

Ah, jacquesm bait, ok here is my solution (left), right one is an alternative to yours. http://imgur.com/a/h7HnB just the tops: http://imgur.com/a/wsqCw
