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

by Petras Vestartas

Apr 27, 2016

Hi,

Is there a better way to use octopus loop to transfer data from the end of definition to the start without using timer for Octopus?

As long as I am using Octopus Loop with Kangaroo Solver, I do not want to change slider manually, but 'update' octopus when output of kangaroo changes.

In general I take one mesh and subdivide one mesh face, then I want to return back the same geometry.

Or is it better just to write recursion function inside one custom component?

Kind Regards,

Petras Vestartas

    Hallo forum! Een neef uit Zwolle vertelde me over zijn winst en dat motiveerde me om zelf ook een poging te wagen online gisteren. Ik had een reeks slechte ervaringen elders en overwoog serieus om voorlopig niet meer in te zetten bij ons op het web. Met b7 casino vond ik echter weer plezier in het pokeren op mijn mobiel gisterenavond. De gokkasten gaven me de grote winst die ik nodig had gisteren.
