# 3-partition problem

The 3-partition problem is a strongly NP-complete problem in computer science. The problem is to decide whether a given multiset of integers can be partitioned into triplets that all have the same sum. More precisely: * The input to the problem is a multiset S of n = 3 m  positive integers. The sum of all integers is . * The output is whether or not there exists a partition of S into m triplets S1, S2, …, Sm such that the sum of the numbers in each one is equal to T. The S1, S2, …, Sm must form a partition of S in the sense that they are disjoint and they cover S. The 3-partition problem remains strongly NP-complete under the restriction that every integer in S is strictly between T/4 and T/2. (Wikipedia).

Partitions of a Set | Set Theory

What is a partition of a set? Partitions are very useful in many different areas of mathematics, so it's an important concept to understand. We'll define partitions of sets and give examples in today's lesson! A partition of a set is basically a way of splitting a set completely into disj
