WebRecursive functions have pretty big overhead compared to iterative methods. The best way to increase speed is to see if it is possible to convert the function into an iterative loop instead of a recursive one. If you can implement the whole thing with gotos, then you should be able to do it with a for/while loop. WebOct 31, 2024 · If you still wanted to maintain the old order as a matter of preference, the recursion can be calculated and saved into a variable first. recursion_res = find_path(...)min_effort = min(min_effort, recursion_res) …
