In this case, the array from which samples are taken is [2, 3, -1, -20, 5, 10]. In computer science, the maximum sum subarray problem, also known as the maximum segment sum problem, is the task of finding a contiguous subarray with the largest sum, within a given one-dimensional array A [1...n] of numbers. It can be solved in time and space.
Ulf Grenander (23 July 1923 – 12 May 2016) was a Swedish statistician and professor of applied mathematics at Brown University.. His early research was in probability theory, stochastic processes, time series analysis, and statistical theory (particularly the order-constrained estimation of cumulative distribution functions using his sieve estimator).
The reactances of synchronous machines comprise a set of characteristic constants used in the theory of synchronous machines. [1] Technically, these constants are specified in units of the electrical reactance (ohms), although they are typically expressed in the per-unit system and thus dimensionless. Since for practically all (except for the ...
The subset sum problem (SSP) is a decision problem in computer science. In its most general formulation, there is a multiset of integers and a target-sum , and the question is to decide whether any subset of the integers sum to precisely .[1] The problem is known to be NP-complete. Moreover, some restricted variants of it are NP-complete too ...
The divide and conquer version of the maximum subarray is notoriously O(n lg n) (see CLRM for instance as a reference.) I have trouble understanding the solution, for instance, what sum[f - 1] and sum[f]? the only array defined clearly in the problem is a, I don't know what sum is supposed to contain. An additional explanation would be great.
The Ruzzo–Tompa algorithm or the RT algorithm[1] is a linear-time algorithm for finding all non-overlapping, contiguous, maximal scoring subsequences in a sequence of real numbers. [2] The Ruzzo–Tompa algorithm was proposed by Walter L. Ruzzo and Martin Tompa. [3] This algorithm is an improvement over previously known quadratic time ...

one of the longest increasing subsequences is. 0, 2, 6, 9, 11, 15. This subsequence has length six; the input sequence has no seven-member increasing subsequences. The longest increasing subsequence in this example is not the only solution: for instance, are other increasing subsequences of equal length in the same input sequence.
