Consider solving your problem with a pair of simpler, more manageable algorithms: one algorithm that reliably creates simple, pre-solved boards and another that rearranges flows to make simple boards more complex. The first part, building a simple pre-solved board, is trivial (if you want it to be) if you’re using n flows on an nxn … Read more

There is a way of deducing the “local path” of a file (more concretely, the string that was used to load the file).
