Convex_hull
It is utils for computing the distance from a target vector to a convex hull.
The following problem can formulate the following QP problem:
$\arg\min_{\lambda_1, \dots, \lambda_n}|x - \lambda_1 y_1 + \dots
- \lambda_n y_n |$
By now, I use scipy, cvxopt, gurobi to implement the algorithm to solve the QP problem.
Please feel free to use it.
