Optimization Service
Optimization
The linear optimization service, used to model and solve linear and mixed-integer linear
programs.
Classes
Methods
| Method | Return type | Brief description |
addConstraint(lowerBound, upperBound) | LinearOptimizationConstraint | Adds a new linear constraint in the model. |
addConstraints(lowerBounds, upperBounds, variableNames, coefficients) | LinearOptimizationEngine | Adds constraints in batch to the model. |
addVariable(name, lowerBound, upperBound) | LinearOptimizationEngine | Adds a new continuous variable to the model. |
addVariable(name, lowerBound, upperBound, type) | LinearOptimizationEngine | Adds a new variable to the model. |
addVariable(name, lowerBound, upperBound, type, objectiveCoefficient) | LinearOptimizationEngine | Adds a new variable to the model. |
addVariables(names, lowerBounds, upperBounds, types, objectiveCoefficients) | LinearOptimizationEngine | Adds variables in batch to the model. |
setMaximization() | LinearOptimizationEngine | Sets the optimization direction to maximizing the linear objective function. |
setMinimization() | LinearOptimizationEngine | Sets the optimization direction to minimizing the linear objective function. |
setObjectiveCoefficient(variableName, coefficient) | LinearOptimizationEngine | Sets the coefficient of a variable in the linear objective function. |
solve() | LinearOptimizationSolution | Solves the current linear program with the default deadline of 30 seconds. |
solve(seconds) | LinearOptimizationSolution | Solves the current linear program. |
Properties
| Property | Type | Description |
Status | Status | Status of the solver. |
VariableType | VariableType | Type of variables created by the solver. |
Properties
| Property | Type | Description |
OPTIMAL | Enum | Status when an optimal solution has been found. |
FEASIBLE | Enum | Status when a feasible (not necessarily optimal) solution has been found. |
INFEASIBLE | Enum | Status when the current model is unfeasible (has no solution). |
UNBOUNDED | Enum | Status when the current model is unbound. |
ABNORMAL | Enum | Status when it failed to find a solution for unexpected reasons. |
MODEL_INVALID | Enum | Status when the model is invalid. |
NOT_SOLVED | Enum | Status when LinearOptimizationEngine.solve() has not been called yet. |
Properties
| Property | Type | Description |
INTEGER | Enum | Type of variable that can only take integer values. |
CONTINUOUS | Enum | Type of variable that can take any real value. |
