Divide Surface (Closed Curve) into Equal area into 3x3 Grid

Hello
or you didn’t really search or what you are after is not clear. Here what I did reusing an example given on the forum

Divide into 115 pieces and 6 different sizes

Yes it is possible there are many strategies. Division with lines using Galapagos for example or making some some division in one axis then in one other … and many mores surely. Search on old forum … Here a solution but there are many other. In the simple way it divided the surface just with one axis, so it slices it. The you can resubdivide it. [image] The idea is to first mesure the surface of slices with equal distribution. The use these surfaces to calculale the good interval for cons…

BUT if you want just 4 lines (2 parallel), I think it is impossible.

Is there a way to divide land plots equally in grasshopper?

Keeping the boundary is simply a matter of adding another goal for this: plot_area2.gh (18.0 KB) [image] Solving a problem like this with Galapagos is a bit like throwing darts at a board, it might solve it to within 5% or so if you wait a few minutes (and as you scale the number of plots this will get much worse), instead of just following the gradient and getting a solution to within 0.0001% in a few milliseconds. Evolutionary solvers are fantastic for some types of problem, where there ar…
