Modify for making the code readable #4574
Description
Sharing Knowledge
In the a_star algorithm, 47th line makes less readable code from my point of view.
f = g + heuristic[init[0]][init[0]]
Moreover, Does heuristic[init[0]][init[0]] not be heuristic[init[0]][init[1]] ?
Two variables x and y have been already initialized by init[0] and init[1]. Doesn't it seem good to read if we make 47th line as below?
f = g + heuristic[x][y]
