- Method Detail
  - getPolicy
```
ResolutionPolicy getPolicy()
```
    Returns:
    
    the ResolutionPolicy of the problem
  - isOptimization
```
default boolean isOptimization()
```
    Returns:
    
    true iff the problem is an optimization problem
  - getBestLB
```
Number getBestLB()
```
    Returns:
    
    the best lower bound computed so far
  - getBestUB
```
Number getBestUB()
```
    Returns:
    
    the best upper bound computed so far
  - updateBestLB
```
void updateBestLB(Number lb)
```
    States that lb is a global lower bound on the problem
    
    Parameters:
    
    lb - lower bound
  - updateBestUB
```
void updateBestUB(Number ub)
```
    States that ub is a global upper bound on the problem
    
    Parameters:
    
    ub - upper bound
  - updateBestBounds
```
default void updateBestBounds(IBoundsManager b)
```
    States that b is global bounds on the problem
    
    Parameters:
    
    b - lower and upper bounds
  - getBestSolutionValue
```
Number getBestSolutionValue()
```
    Returns:
    
    the best solution value found so far (returns the initial bound if no solution has been found yet)
  - resetBestBounds
```
default void resetBestBounds()
```
    Reset best bounds to the initial domain of the objective variables
