Do you understand how a dictionary is ordered?
The word “abet” comes before “about” why.
That is Lexicographic Ordering.
If we have lexicographic ordering on here are some examples.
I hope this give some guidance that helps you.
What is this? It seems alittle confusing compared to other forms of ordering.
If we have Lex. ordering on r on A X B determined by linear order r1 on A and r2 on B. Then it would be true that if both r1 and r2 are well founded then so is r. Correct?
