Object storing a linear constraint of the formlowerBound ≤ Sum(a(i) x(i)) ≤ upperBoundwherelowerBound andupperBound are constants,a(i) are constantcoefficients andx(i) are variables (unknowns).

The example below creates one variablex with values between0 and5and creates the constraint0 ≤ 2 * x ≤ 5. This is done by first creating a constraintwith the lower bound5 and upper bound5. Then the coefficient for variablex in this constraint is set to2.

constengine=LinearOptimizationService.createEngine();// Create a variable so we can add it to the constraintengine.addVariable('x',0,5);// Create a linear constraint with the bounds 0 and 10constconstraint=engine.addConstraint(0,10);// Set the coefficient of the variable in the constraint. The constraint is now:// 0 <= 2 * x <= 5constraint.setCoefficient('x',2);

setCoefficient(variableName, coefficient)

constengine=LinearOptimizationService.createEngine();// Create a linear constraint with the bounds 0 and 10constconstraint=engine.addConstraint(0,10);// Create a variable so we can add it to the constraintengine.addVariable('x',0,5);// Set the coefficient of the variable in the constraint. The constraint is now:// 0 <= 2 * x <= 5constraint.setCoefficient('x',2);
