Graphshortestpath 需要 bioinformatics toolbox。
WebMar 31, 2014 · 1) Think of every pixel in the maze as node on a connected graph. 2) Define the walls as having high weights. This ensures that walls will act as separators. 3) Use a 4-connected neighborhood to link adjacent pixels/nodes. 4) Convert the maze image into a sparse Distance matrix (similar to an adjacency matrix with weights instead of ones).

WebMar 6, 2024 · "Although any given solution to an NP-complete problem can be verified quickly (in polynomial time), there is no known efficient way to locate a solution in the first place; the most notable characteristic of NP-complete problems is that no fast solution to them is known. That is, the time required to solve the problem using any currently known … WebApr 30, 2015 · Learn more about bioinformatics, shortestpath, bellman-ford, longestpath .
