Ask HN: Why is big O often used in CS when omega or theta should be used?

2•amichail•11mo ago
Do most people not know about omega and theta or perhaps they intentionally misuse asymptotic notation?

Comments

adrianN•11mo ago
Finding lower bounds is generally more difficult.
amichail•11mo ago
People often use big O notation in all cases including for lower bounds.
adrianN•11mo ago
BigO for lower bounds is plain wrong
numpad0•11mo ago
Those aren't in the ASCII table.
compressedgas•11mo ago
I've found some people on a well known QA site to be so strict with big-O notation that I don't use it anymore and instead only refer to constant, linear, quadratic time and so on. Even when O(1), O(n), O(n^2) would be actually easier to write even if they are technically wrong.
