Description

Octopus is a plug-in for applying evolutionary principles to parametric design and problem solving. It allows the search for many goals at once, producing a range of optimized trade-off solutions between the extremes of each goal.

Also see octopus.E for custom evolutionary algorithms.

It is part of a range of tools developed at the University of Applied Arts Vienna, and Bollinger+Grohmann Engineers.

 

  • search for single goal + diversity of solutions
  • search for best trade offs between 2 to X goals
  • improve solutions by similarity-goals
  • choose preferred solutions during a search
  • change objectives during a search
  • solutions' 3d models for visual feedback
  • recorded history
  • save all search data within the Grasshopper document
  • save a solution as a Grasshopper State
  • export to text or text files


Octopus introduces multiple fitness values to the optimization. The best trade-offs between those objectives are searched, producing a set of possible optimum solutions that ideally reach from one extreme trade-off to the other.

Based on SPEA-2 and HypE from ETH Zürich and David Rutten's Galapagos User Interface. Developed by Robert Vierlinger in cooperation with Christoph Zimmel, karamba3d.com and Bollinger+Grohmann Engineers.

 

To install:

  • Copy the .gha and .dll file into the Grasshopper components folder 
  • Right-click the file > Properties > make sure there is no "blocked" text
  • Restart Rhino and Grasshopper

 

Some examples are provided here. 

New commented examples and a brief manual are provided in the download of octopus on food4rhino.

Octopus Loop - How to use

by Theodora Georgopoulou

Jun 3, 2020

Hello everyone,

very new to grasshopper, I want to repeat a process taking place on a grid multiple times using a Loop. I did it using the Anemone Loop which was great and easier for me to understand, but gets very slow when I increase the grid cells. So I decided to use the Octopus Loop, but my problem is that I don't get how it works. I don't understand what do I need to connect to the bottom wire entrances and how. I read the Manual and googled a lot, but no results.

Could anyone give me some insight or give a link where I can find it out?

best

theodora

      Hey, I’ve been deep into learning Grasshopper too, and after getting stuck on loops for a while, I decided to take a break and stumbled upon felixspin. I tried the Mega Reel slot, and after a few frustrating spins, I finally hit a solid win that made the whole session fun. The games run smoothly, and I especially liked that they offer bonuses for players from Canada, which made it even more enjoyable. It was a great way to clear my head before diving back into complicated loops.

        Ich saß neulich in einem Café in Düsseldorf und habe in einem Blog über modernes Gaming gelesen. Dort wurde play jonny als Geheimtipp für SLOTS ONLINE erwähnt, also habe ich es direkt auf meinem Tablet ausprobiert. Die Spiele laufen flüssig und die Auswahl ist gigantisch. Ich hatte gestern Glück und konnte einen schönen Gewinn erzielen, der meine Erwartungen übertroffen hat. Ich bin mit dem gesamten Service und der Seite wirklich sehr zufrieden.
