WebThe evasion probability of the smuggler's optimal path is 6.341943e-03, or 0.634%. We run a discrete graph-theoretic shortest path algorithm on the same graph to check that we get the same optimal path. The function optPath is using the NetworkX Python package and Dijkstra’s_algorithm to compute the optimal path. WebThe quadratic program is defined as: minimize x 1 2 x T P x + q T x subject to G x ≤ h A x = b l b ≤ x ≤ u b. using the QP solver selected by the solver keyword argument. Parameters: P ( Union [ ndarray, csc_matrix ]) – Symmetric cost matrix (most solvers require it to be definite as well). q ( ndarray) – Cost vector.
