NettetMixed-integer linear programming is an extension of linear programming. 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. NettetTheorem 1: Let a and b be nonzero integers. Then the smallest positive linear combination of a and b is a common divisor of a and b. Theorem 2: Let a and b be … NettetAs it turns out (for me), there exists an Extended Euclidean algorithm. This algorithm computes, besides the greatest common divisor of integers a and b, the coefficients of Bézout's identity, that is, integers x and y such that So it allows computing the quotients of a and b by their greatest common divisor. rocherlea tas
