For eg. {{a, b}, {c, d}} is refinement of {a, b, c, d} But {{a, b}, {c, d}} is not refinement of {{a, b,c}, {d}}... We can also say that P3 is refinement over P2 OR P3 is refinement of P2 OR P2 is coarser (opposite of refinement) than P3 I hope you will understand.. 0 votes 0 votes Please log in or register to add a comment.
