I agree to Russel. Cause usually assembly lines are not necessarily linear. Its
beneficial to have parrallel assesmbly.
Another fact is complexity is determined by spatial location and orientation of
the brick, number of degree of freedom it has in this configration and maybe
alternative sequences possible to arrive at this configration. Not always is it
the case that a lego design is layered. Thus acessebilty of everybrick is very
different in different designs.

Yes, but what happens if you could construct the structure in fewer steps by
parallelizing the process. It seems that this approach will take into account
any inherent repetitiveness within the building process. I think the complexity
of a process should include these type of details which may be left out of any
straight forweard approach.

Could it be as simple (and I'm only half serious) as smashing the structure and counting the bricks? LOL each brick requires one assembly step so:
number of bricks = number of assembly steps = complexity

Are you looking for some kind of absolute Reduction algorithm (proven
mathematically) that can rate how complex a lego structure is?

Hello all,
I am a senior Robotics student studying assesmbly planning algorithms. I
am looking at mechanism designing using Contact Space. I wanted to know does
there exsist tools which can determine complexity of a lego mechanism (on the
bases of disassembly sequences) or any realted stuff.
Thanks
Manu
