Well, yes, the (end, :) can only work as indexing so should follow the name of a variable but comes after a ;.
On top of that, even if that didn't produce an error, you'd have the error that you try to add a cell array to something. + (addition) is not defined for cell arrays.
All in all, I've no idea what that 2nd line is supposed to do.

Assuming the cell in question has coordinates x, y, then
next = [x-1, y;
x, y+1;
x+1, y;
x, y-1];
would do what you want, if I understood correctly.
Note: I missed at first, that it appears that you're confusing x, y and row, column. Traditionally, x is the horizontal coordinates which would correspond to column, and y the vertical up which would correspond to row (or better height - row). So your ind2sub call should probably read:
[newy, newx] = ind2sub([nrow, ncol], candidates(whichleast)); %note the inversion: [y,x] not [x,y]

I don't think
a. Square brackets are allowed on the RHS
b. Round brackets are allowed on the LHS
Hope this helps.
Thank you for formally accepting my answer

"I don't think"
"a. Square brackets are allowed on the RHS"
a = [1,2];
"b. Round brackets are allowed on the LHS"
a(2) = 3;
