Integer linear combination

Did you know?

In mathematics, a linear combination is an expression constructed from a set of terms by multiplying each term by a constant and adding the results (e.g. a linear combination of x and y would be any expression of the form ax + by, where a and b are constants). The concept of linear combinations is central to linear algebra and related fields of mathematics. Most of this article deals with linear combinations in the context of a vector space over a field, with some generalizations given at the … NettetFor any nonzero integers a and b, there exist integers s and t such that gcd (a, b) = as + bt. Moreover, gcd (a, b) is the smallest positive integer of the form as + bt. I know of …

It handles problems in which at least one variable takes a discrete integer rather than a continuous value. Although mixed-integer problems look similar to continuous variable problems at first sight, they offer significant advantages in terms of flexibility and precision.
