在图论中,无论是 directed 还是 undirected 图,找 cycle/loop 都是很困难的一件事【都不说找所有的 cycle 了,找单个 cycle 都(⊙o⊙)…】。 但是感谢互联网, ,可以找到很多可用代码,比如在这个 so 问题下: Finding all cycles in undirected graphs 算法 Optimal Listing of Cycles and st-Paths in Undirec...

A toroid is a solenoid wrapped to form a circle. a) Calculate the magnetic field in a toroid of 600 turns with radius r of 0.5 \ m when 0.76 \ A of current flowing through it, b) Calculate the magnetic field outside the toroid, c) Sketch the graph of B(r) ...
is the NB matrix. Both left and right eigenvectors can be thought of as two sets of messages traveling along the directed edges of the network. This becomes more apparent if we transform Eqs (4, 5) in dynamical updating rules for the messagesLi→jandRi→jas: ...
In [36], a method used laser range and unique April tag based visual context measurements in a graph SLAM framework. Robot localization was then performed using only the April tags. In [37], a SLAM method used a reinforcement learning policy to switch between localizing with an occupancy ...
In a directed graph, we start at some node and every turn, walk along a directed edge of the graph. If we reach a node that is terminal (that is, it has no outgoing directed edges), we stop. Now, say our starting node iseventually safeif and only if we must eventually walk to ...
