Asymptotic Relations and Notation
- Big O:
g(n) <= O(f(n)) iff
there exist positive constants c and n0
such that 0 <= g(n) <= cf(n) for all n >=
n0
"g is asymptotically bounded above by f "
-
Big Omega:
g(n) >= Ω(f(n)) iff there exist positive constants
c and n0 such that
0 <= cf(n) <= g(n) for all n >=
n0
"g is asymptotically bounded below by f "
-
Big Theta:
g(n) = Θ(f(n)) iff
there exist positive constants c1, c2,
and n0 such that
0 <= c1f(n) <= g(n) <= c2f(n) for all n >=
n0
"g is asymptotically bounded above and below by f "
