algorithmic modeling for Rhino



Wallacei (which includes Wallacei Analytics and Wallacei X) is an evolutionary engine that allows users to run evolutionary simulations in Grasshopper 3D through utilising highly detailed analytic tools coupled with various comprehensive selection methods, including algorithmic clustering, to assist users to better understand their evolutionary runs, and make more informed decisions at all stages of their evolutionary simulations; including setting up the design problem, analysing the outputted results and selecting the desired solution or solutions for the final output. Wallacei also provides users with the ability to select, reconstruct and output any phenotype from the population after completing their simulation.


The free plugin is streamlined to give users efficient access to the data outputted by their evolutionary simulations, and enable clear and efficient methods for analysis and selection – The aim is for users (of all degrees of expertise) to better understand their evolutionary simulations, gain a thorough understanding of the outputted numeric values, and seamlessly extract the optimised data; all within one user interface.


Wallacei X employs the NSGA-2 algorithm (Deb et. al., 2001) as the primary evolutionary algorithm, and utilises the K-means method as the clustering algorithm. Additionally, Wallacei X incorporates the JMetal, LiveCharts and HelixToolkit libraries.

Wallacei is founded on the research conducted by Mohammed Makki during his Doctoral studies at the Architectural Association under the directorship of Dr. Michael Weinstock; and has been developed by Mohammed Makki, Milad Showkatbakhsh and Yutao Song.


Although Wallacei has been streamlined for Rhino 6, the plugin can also be installed in Rhino 5 (both 64 and 32 bit platforms).

Resume the simulation is it possible? 9 Replies

Hi,Can we resume the simulation from the point where Rhino crashes. I noticed that the Wallacie passes through the same solutions if we do not change the seed number. If it is possible , how please? Continue

Setting population and generation 6 Replies

Hi, I made a simple example to learn how generative design with Wallacei works. I made a solid extruded from a square with a 1-20 slider for the height. I set a '0' value to all the solution up to 10…Continue
