선형최적화제약조건
lowerBound ≤ Sum(a(i) x(i)) ≤ upperBound
형식의 선형 제약 조건을 저장하는 객체입니다. 여기서 lowerBound
및 upperBound
는 상수이고, a(i)
는 상수 계수이며, x(i)
는 변수 (알 수 없는 수)입니다.
아래 예에서는 값이 0
과 5
사이인 x
변수 하나를 만들고 0 ≤ 2 * x ≤ 5
제약 조건을 만듭니다. 먼저 하한 5
및 상한 5
으로 제약 조건을 만든 다음 그러면 이 제약 조건에서 x
변수의 계수가 2
로 설정됩니다.
const engine = LinearOptimizationService.createEngine();
// Create a variable so we can add it to the constraint
engine.addVariable('x', 0, 5);
// Create a linear constraint with the bounds 0 and 10
const constraint = engine.addConstraint(0, 10);
// Set the coefficient of the variable in the constraint. The constraint is now:
// 0 <= 2 * x <= 5
constraint.setCoefficient('x', 2);

setCoefficient(variableName, coefficient)
제약 조건에서 변수의 계수를 설정합니다. 기본적으로 변수의 계수는 0입니다.
const engine = LinearOptimizationService.createEngine();
// Create a linear constraint with the bounds 0 and 10
const constraint = engine.addConstraint(0, 10);
// Create a variable so we can add it to the constraint
engine.addVariable('x', 0, 5);
// Set the coefficient of the variable in the constraint. The constraint is now:
// 0 <= 2 * x <= 5
constraint.setCoefficient('x', 2);
