the entire file except the last one has a response using the r0 cells_base search and nothing using the RCX search.
The last one is reverse : no response with the cells-base search, but a RCX solution

may-be leren will have other results.

I am also interested in getting the rows/columns/boxes equivalence to the cells solution

I coded Multifish and ran the puzzle list, resulting in the following:

BTW:
Hi Leren:Can your code find equivalent multiple fish for all puzzles with MSLS?
