  2. 2Sum - Wikipedia

    en.wikipedia.org/wiki/2Sum

    2Sum and its variant Fast2Sum were first published by Ole Møller in 1965. [2] Fast2Sum is often used implicitly in other algorithms such as compensated summation algorithms ; [ 1 ] Kahan's summation algorithm was published first in 1965, [ 3 ] and Fast2Sum was later factored out of it by Dekker in 1971 for double-double arithmetic algorithms ...

  3. Subset sum problem - Wikipedia

    en.wikipedia.org/wiki/Subset_sum_problem

    The subset sum problem (SSP) is a decision problem in computer science. In its most general formulation, there is a multiset S {\displaystyle S} of integers and a target-sum T {\displaystyle T} , and the question is to decide whether any subset of the integers sum to precisely T {\displaystyle T} . [ 1 ]

  4. Maximum subarray problem - Wikipedia

    en.wikipedia.org/wiki/Maximum_subarray_problem

    Maximum subarray problems arise in many fields, such as genomic sequence analysis and computer vision.. Genomic sequence analysis employs maximum subarray algorithms to identify important biological segments of protein sequences that have unusual properties, by assigning scores to points within the sequence that are positive when a motif to be recognized is present, and negative when it is not ...

[ 1 ] LeetCode has gained popularity among job seekers in the software industry and coding enthusiasts as a resource for technical interviews and coding ...

  6. Floating-point error mitigation - Wikipedia

    en.wikipedia.org/wiki/Floating-point_error...

    Variable length arithmetic represents numbers as a string of digits of a variable's length limited only by the memory available. Variable-length arithmetic operations are considerably slower than fixed-length format floating-point instructions.

  7. Multiple subset sum - Wikipedia

    en.wikipedia.org/wiki/Multiple_subset_sum

    The multiple subset sum problem is an optimization problem in computer science and operations research. It is a generalization of the subset sum problem . The input to the problem is a multiset S {\displaystyle S} of n integers and a positive integer m representing the number of subsets.

  8. Erdős–Szemerédi theorem - Wikipedia

    en.wikipedia.org/wiki/Erdős–Szemerédi_theorem

    The sum-product problem is particularly well-studied over finite fields. Motivated by the finite field Kakeya conjecture , Wolff conjectured that for every subset A ⊆ 픽 p , where p is a (large) prime, that max(| A + A |, | AA |) ≥ min( p , | A | 1+ ε ) for an absolute constant ε > 0 .

  9. Partition problem - Wikipedia

    en.wikipedia.org/wiki/Partition_problem

    The partition problem is NP hard. This can be proved by reduction from the subset sum problem. [6] An instance of SubsetSum consists of a set S of positive integers and a target sum T; the goal is to decide if there is a subset of S with sum exactly T.
