Extended convex hull
Websolution and the Newton-Raphson method can be applied to find it. If the convex hull constraint is violated, the algorithm does not converge with ∥¼∥increasing as the iteration proceeds. Hence, it can be computationally more efficient to minimize r⋆(¼) first to get log(R(¹)) and indirectly check the convex hull constraint by ... WebJul 21, 2015 · The neighbourhood type convex hull has a large mean area size, particularly for the rural samples. Comparing convex hull with path area, which are both based on GPS tracking, reveals a 25% higher supermarket exposure for the convex hull neighbourhood type. However, if the area sizes for both neighbourhood types are used to adjust the …
