Evolving Truss Structures Using Genetic Algorithms

you have some great stuff here

[MrJonkelp]

very interesting video thanks

[samjenkinssam]

really informative and interesting

Might be interesting to see what kind of structure would evolve if you make the direction of gravity continuously change, by a few degrees on each generation

[LongerGrass]

Good work!

Notice this important thing about genetic algorithms. They do not always optimize for the constraints. They seem to, but unless you test every possibility, or at least know special information of what you test, there could be a better solution that you missed. Remember, it's like finding a point in a large multidimensional graph, once you start towards one 'solution', its like a black hole. Now, I think that if you mix dozens of different solutions together in a complex one, you can find better

it looked like they were dancing, kinda.

Durr hurr, the vestigal structure wasn't completely useless since it still provides some support, therefore it wasn't vestigal, durr hurr

My impression of a certain type of weak criticism.

[ZongyiYang]

@tifforo1 You are probably correct, lol. Looking it over, vestigial was not a good word choice. I wanted to point out that the genetic algorithm did not find the most efficient solution, just one that works. It got stuck with a non-optimal solution near the base there, the most optimal solution should be just a bunch of triangles. However, like that laryngeal nerve in giraffes, it had to make do with what it has. It would take an incredibly rare mutation to optimize that bit.

@ZongyiYang

I was trying to imitate the creationists who say things like "the tailbone isn't vestigial because muscles connect to it."

[jpp7233]

Hi. Did you create this program for a master´s degree?

What is your background: civil engineering?

Thanks.

[ZongyiYang]

@jpp7233 I made this program in between 1st and 2nd year of Engineering Science. I am currently in 3rd year Engsci in the Electrical and Computer option. I had a Civ102 course in year 1 so I had some background knowledge of trusses.

[WhatIsGod]

do you have anything more that is even close to this? im going into engineering and this is one of the most beautiful things i have ever seen!

[ZongyiYang]

@WhatIsGod The program was initially made for bridges, but 4 bridges didn't fit in a video so I changed it to select for height. I don't have a vid for it, but maybe next summer break I'll find the time to dig up this code from my archives and make a new vid

it looks like they are dancing... awesome! :D

[Pityugonzales]

Really cool, I'm just making a simulation like this,

I make diffusion genetic algorithms, on bridge structures... Based on BridgeBuilding games... :)

Anyway really coool stuff

[Ultravampire]

what song used in soundtrack?

[ZongyiYang]

@Ultravampire Hrm, I seem to have forgotten to put the source. I swear I did, but it was soo long ago. I got it from this youtube video (add youtube . com to the beginning):

[TheGradiusFan]

I hope you make more simulations :3

[tronom90]

Whoa, that's awesome! What programming language do you use? I started on neural networks and genetic programming with java, but my graphic skills are to low to make some nice animations of the stuff i'm doing

[ZongyiYang]

I used C++ with openGL. I agree that drawing stuff in Java is confusing. For the openGL, I remember searching for "openGL video tutorial" on google and it brought me to a step by step video guide on how to use it.

[AlexPleaseHelpDotCom]

Awesome stuff again.

Do one about how to evolve an ideal healthcare system. ;)
