Euclidean path.

A continuous latent space allows interpolation of molecules by following the shortest Euclidean path between their latent representations. When exploring high dimensional spaces, it is important to note that Euclidean distance might not map directly to notions of similarity of molecules.When separate control strategies for path planning and traffic control are used within an AGV system, it is unknown how long it is going to take for an AGV to execute a planned path; often the weights in the graph cannot effectively reflect the real-time execution time of the path (Lian, Xie, and Zhang Citation 2020).
