Method Summary

All Methods Instance Methods Abstract Methods Default Methods
Modifier and Type	Method	Description
`void`	`fixSomeVariables()`	Freezes some variables in order to have a fast computation.
`default void`	`init()`	Initialize this neighbor
`default boolean`	`isSearchComplete()`
`void`	`loadFromSolution(Solution solution)`	Load a solution and record it
`void`	`recordSolution()`	Record values of decision variables to freeze some ones during the next LNS run
`default void`	`restrictLess()`	Use less restriction at the beginning of a LNS run in order to get better solutions Called when no solution was found during a LNS run (trapped into a local optimum)

- Method Detail
  - init
```
default void init()
```
    Initialize this neighbor
  - recordSolution
```
void recordSolution()
```
    Record values of decision variables to freeze some ones during the next LNS run
  - fixSomeVariables
```
void fixSomeVariables()
               throws ContradictionException
```
    Freezes some variables in order to have a fast computation. The fixed variables are declared as decisions in the decision path.
    
    Throws:
    
    ContradictionException
  - restrictLess
```
default void restrictLess()
```
    Use less restriction at the beginning of a LNS run in order to get better solutions Called when no solution was found during a LNS run (trapped into a local optimum)
  - isSearchComplete
```
default boolean isSearchComplete()
```
    Returns:
    
    true iff the search is in a complete mode (no fixed variable)
  - loadFromSolution
```
void loadFromSolution(Solution solution)
```
    Load a solution and record it
    
    Parameters:
    
    solution - a solution to record
