A problem is called 3SUM-hard if solving it in subquadratic time implies a subquadratic-time algorithm for 3SUM. The concept of 3SUM-hardness was introduced by Gajentaan & Overmars (1995).

The 3SUM problem tries to identify 3 integers $a,b,c$ from a set $S$ of size $n$ such that $a + b + c = 0$. It is conjectured that there is not better solution than ...
Therefore, to prove that 3SUM can be solved in expected time O(n2−ε) O (n 2 ε) over every universe size u u of integers, it suffices to give an algorithm that solves 3SUM on every universe of size O(n3) O (n 3) in expected time O(n2−ε) O (n 2 ε).
3SUM-hardness A problem is called 3SUM-hard if solving it in subquadratic time implies a subquadratic-time algorithm for 3SUM. The concept of 3SUM-hardness was introduced by (Gajentaan Overmars). They proved that a large class of problems in computational geometry are 3SUM-hard, including the following ones.

6 (this is a follow-up of my previous question, which uses the 3SUM' problem instead of 3SUM) Suppose we have a list S S of n n integers. Usually, for 3SUM, we only determine if there exist a a, b b, c c ∈ S ∈ S such that a + b + c = 0 a + b + c = 0.

Unfortunately, it is not known whether Average is (even weakly) 3SUM-hard! I suspect that Average is actually 3SUM-hard, if only because the (2) () lower bound for Average is harder to prove than the (2) () lower bound for 3SUM. You also ask about the special case where adjacent array elements differ by less than some fixed integer K K.

I've recently encountered a new (for me) notion from computational complexity theory called 3-SUM hardness which is based on the conjecture that 3-SUM problem can not be solved in O(n2−ε) O (n 2 ε) time where n n is the number of reals among which we should check whether three of them sum to zero.
Our ideas can also lead to a faster O((n2= log2 n)(log log n)O(1))-time algorithm for this problem. Geometric 3SUM-Hard Problems. The importance of 3SUM stems from the many problems that were shown to be 3SUM-hard, starting with the seminal paper by Gajentaan and Overmars [20] in computational geometry.

In particular, if we reduce 3-SAT to a 3SUM instance of size $2^ {O (n)}$, it will not refute ETH, and if we reduce 3-SAT to a 3SUM instance of size $2^ {o (n)}$, it will refute ETH regardless of the complexity of 3SUM. [1] Virginia V. Williams.
If Convolution 3SUM is in T (n) time, then 3SUM is in randomized O(T (n)) time. Proof sketch. The idea is take a random hash function for R = n and put each number x 2 A at position ah(x) = x. An issue is that there will be multiple numbers hashing to the same value. To deal with that we let each position ai to become a bucket storing many numbers.

6 Consider the 3SUM problem: given a set $S$ of $n$ numbers identify $x$,$y$,$z$, s.t $x + y = z$. It is believed that the simple $O (n^2)$ algorithm is the best possible; reductions from 3SUM have been used to prove lower bounds for other problems assuming 3SUM is hard [Patrascu 2010].
