Problem in making Path Finder satisfied Slope of the Ramp

[JO13 (JO)]

1. Depending on the slope of the terrain, I want to find the optimal route while satisfying an slope of the ramp. This is my expectation.

2. But the result is… I hate zig zag result (Divide Curve Count : 50)

3. If I increase the segments, results are getting worse, tighter zig-zag (Divide Curve Count : 100)

4. On the contrary, If I reduce segments it’s getting better. It’s a little bit similar to what i imagine (Divide Curve Count : 20)

5. But in another case, If the straight distance is steep, it can’t think of going around and almost climb a cliff. I want smooth path even if it goes longer way like a path in a park.

6. And I want to find best route while satisfying the max slope(5.5%) using Galapagos, I don’t know what values to put into the Fitness Input value, how to accomplish this.

I recategorized your topic so it is in the Kangaroo category.

And have you looked at this topic?

I think it helps to think about the geometric aims here and when they conflict. If the target length is low, this keeps the curve closer to a straight line. Clearly a straight line cannot lie between the 2 fixed end points on the curving surface - just because a destination is 100m away at 10m greater elevation doesn’t mean a route exists that can drive you there at a constant 1:10 slope. Because the 2 aims are conflicting, their relative strengths will control which one is violated more. If …

I got a lot of help from this forum to make this script, I’ll take a look at it again, thanks you!
